Educators traditionally are expected to contribute to the areas of teaching, service and research - the academic trinity. Those kinder administrative souls have noted that contributions in two of these areas are acceptable. Even so, few make significant contributions to even one of these areas and only a small handful make significant contributions to a l l three areas. Professor Doctor Herman Francis Mark is one of these exceptional educators who has and continues to contribute significantly to a l l three areas. He continues to actively review research areas and to consult (research), to speak to learned and popular audiences (teaching) and to edit the Journal of Polymer Science and associated journals (service). The development of polymer education in the USA will be traced using specific examples to illustrate general trends, developing briefly Professor Mark's many contributions to the growth of polymer education. Many others have made significant contributions to polymer education, but in this brief paper only a few of these individuals or centers of learning can be noted. Polymers are i n t e g r a l p a r t s o f mankind as b u i l d i n g blocks o f himself ( p r o t e i n , n u c l e i c a c i d s ) , h i s c l o t h i n g (wool, cotton, p o l y e s t e r ) , b u i l d i n g m a t e r i a l s (wood, p o l y s t y r e n e ) , i n the accumul a t i o n o f knowledge (paper, i n k ) , e t c . The polymer i n d u s t r y today i s a t p a r i t y with the t o t a l metal-based i n d u s t r y and employs more chemists than a l l the other areas of chemistry combined.

POLYMER SCIENCE

OVERVIEW

Tomorrow o f f e r s new f r o n t i e r s i n a l l major areas of macromolecular science with new b u i l d i n g m a t e r i a l s , automobiles and other v e h i c l e s c o n s i s t i n g mostly of polymeric m a t e r i a l s , polymeric space ship wrappings, new s y n t h e t i c organs, f u r t h e r u n r a v e l i n g of biomacromolecules, e t c . A g r e a t e r focus w i l l be placed on the use of n a t u r a l , regenerable polymers as s t o c k p i l e s of nonregenerable feedstocks d i m i n i s h . Polymer chemistry i s a l s o important because (a) i t serves as a b a s i s of many r e l a t e d i n d u s t r i e s such as ceramics, t e x t i l e s and leather, (b) i t s p r i n c i p l e s are a p p l i c a b l e to m a t e r i a l s i n general, and (c) i t s p r i n c i p l e s are v i t a l to biochemistry and medicine. Polymers are l a r g e molecules, o f t e n c a l l e d macromolecules, bound by covalent bonds. The t r a n s m i t t a l of both the general and s p e c i f i c p r o p e r t i e s that c o n t r i b u t e e s p e c i a l l y to the understandi n g of l a r g e molecules and t h e i r s y n t h e s i s i s polymer education. I n f o r m a l l y , education occurs mainly through the w r i t t e n word-journ a l s , books; v i s u a l l y - l a b o r a t o r y demonstrations, movies, s l i d e p r e s e n t a t i o n s ; and the spoken work-classroom p r e s e n t a t i o n s , short courses, seminars, l e c t u r e s e r i e s , d i s c u s s i o n groups. Education occurs both i n f o r m a l l y by d i s c u s s i o n of research problems or s o l u t i o n s with f e l l o w workers, reading the l a t e s t monograph and forma l l y by a t t e n d i n g c l a s s e s , l e c t u r e s e r i e s , e t c . While elements of a l l of the above w i l l be considered, emphasis w i l l be placed on the academic aspects of polymer education. F i n a l l y , the importance of polymer education cannot be separated from i t s importance i n i n d u s t r y and the " r e a l world" - yet u n f o r t u n a t e l y t h i s i s what has and o f t e n continues to be done. P r i o r to 1940 there was l i t t l e or no education d i r e c t e d t o ward polymer chemistry. With the c o n t r i b u t i o n s of Carothers and others that transformed the p r a c t i c e of polymers i n t o a s c i e n c e , and with the l e a d e r s h i p of Herman Mark and others ( i n f o r m a l graduate and postgraduate), polymer education took root but r a p i d expansion and general acceptance by more t r a d i t i o n a l l y o r i e n t e d academic i n s t i t u t i o n s was slowed by many b a r r i e r s . Only s i n c e 197 * has there been a concerted e f f o r t to i n c l u d e education i n the b a s i c concepts of polymer chemistry i n t o the undergraduate c u r r i c u l u m .

Much of the e a r l y development of s c i e n c e , i n c l u d i n g polymer chemistry i n the USA, focused on " a p p l i c a t i o n " of n a t u r a l materia l s to our needs - c o t t o n , wood, f l a x , rubber, cottonseed o i l , l i n s e e d o i l , and wool. Devoe and Raynolds (now a d i v i s i o n of the Celanese Corporat i o n ) has been making p a i n t i n New York s i n c e about 1754, the decades p r i o r to our independence. I t may have been the o l d e s t c o r p o r a t i o n i n the USA. The f i r s t s u c c e s s f u l f a c t o r y was a cotton m i l l , under Samuel S l a t e r , which began to produce on December 21, 1790. In 1814 the w o r l d s f i r s t f a c t o r y to convert raw cotton i n t o c l o t h by power machinery w i t h i n the w a l l s of one b u i l d i n g was erected i n Waltham, Massachusetts by the Boston Manufacturing Company. Lowell, Massachusetts, now the home of Lowell U n i v e r s i t y which i s a center o f polymer education, was the f i r s t American m i l l c i t y employing the Pawtucket F a l l s of the Merrimack R i v e r f o r power. Charles Goodyear's d i s c o v e r y of the v u l c a n i z a t i o n of rubber i n 1839 was one of the most p e r p l e x i n g and exasperating, yet important, t a l e s i n U.S. history. The f i r s t s y n t h e t i c polymer u t i l i z e d on a l a r g e commercial s c a l e was Bakélite produced by Leo Baekeland, one of many f o r e i g n born s c i e n t i s t s who helped c r e a t e American technology. By 1909 he had demonstrated a number of Bakélite a r t i c l e s to members of the r e c e n t l y formed Chemists Club of New York.

These e a r l y courses concent r a t e d on adhesives, o i l s and c o a t i n g s , r e s i n s , t e x t i l e s , paper and pulp and n a t u r a l rubber.

The Mark Connection - 1930's to

1974

The vast m a j o r i t y of polymer education focused on graduate and postgraduate education from the l a t e 1930's to 1974. Early progress was delayed because of World War I I . For many chemists experimenting i n such d i v e r s e areas as perfumes, n a t u r a l products, drugs, s t e r o i d s , d y e s t u f f s , the end product i n c l u d e d some waxy, gooey "glop".

POLYMER SCIENCE

OVERVIEW

Many of us date P r o f e s s o r Mark's c o n t r i b u t i o n s to polymer education and s c i e n c e as beginning i n 1940 with h i s a r r i v a l a t Brooklyn P o l y t e c h n i c . T h i s i s only because we have not recognized the pages of s c i e n t i f i c d i s c o v e r y p r i o r to the coming of the Geheimrat to the USA. A f t e r r e a d i n g s e v e r a l accounts of P r o f e s s o r Mark's l i f e I am tempted to t a c k l e a b i o g r a p h i c a l sketch of h i s l i f e along with n e g o t i a t i n g f o r him, with the Geheimrat's permission, of course, a c o n t r a c t to have i t made i n t o a motion p i c t u r e . (I h i g h l y recommend t c you the two a r t i c l e s w r i t t e n by Morton M. Hunt f o r the New Yorker i n 1958. These are fast-moving, d e l i g h t f u l and even t r u e . ) Even so, my task permits me to b r i e f l y r e c a l l only glimpses of h i s "candle which continues to burn so b r i g h t l y on the stage of l i f e " . He was born Herman F r a n c i s Mark i n Vienna, A u s t r i a on May 3, 1895, the o l d e s t of three c h i l d r e n . His mother was a Viennese Lutheran and h i s f a t h e r a p h y s i c i a n of the o l d f a m i l y - d o c t o r v a r i e t y . Even as a c h i l d h i s z e a l f o r l i f e and z e s t f o r l i v i n g l i f e to i t s f u l l e s t was evident. He played t e n n i s and soccer as o f t e n and l o n g as h i s playmates could endure and then ran 2 to 3 miles about a c i n d e r t r a c k and then two m i l e s to reach home i n time f o r supper. He became i n f e c t e d with the l o v e of chemistry through a v i s i t to the chemistry l a b o r a t o r i e s at the U n i v e r s i t y of Vienna when he v i s i t e d i t with a c l o s e f r i e n d , Gerhard K i r s c h , whose f a t h e r was a p r o f e s s o r of chemical technology at the U n i v e r s i t y . Gerhard and Herman assembled a f a i r l y r e s p e c t a b l e assembly of glassware, chemi c a l s , Bunsen burners and chemistry books during the next few years. At eighteen, Mark decided to get h i s compulsory m i l i t a r y s e r v i c e term over before a t t e n d i n g c o l l e g e . He j o i n e d the e l i t e A l p i n e i n f a n t r y u n i t , the Kaiserschutzen Regiment and i n 1914 part i c i p a t e d i n the b i t t e r b a t t l e s of Lvov and Przemysl where he became h i g h l y decorated f o r bravery i n c l u d i n g a shrapnel wound i n the ankle which r e q u i r e d two months' t r a c t i o n . He then r e j o i n e d the Kaiserschutzen and served f o r three and a h a l f years on the I t a l i a n f r o n t , r i s i n g through the ranks to l i e u t e n a n t . In 1918 he was captured, l e a d i n g to a " s t r a n g e r - t h a n - f i c t i o n " escape i n 1919, coming home to h i s Vienna to l e a r n that he was the most decorated company-grade o f f i c e r i n the A u s t r i a n Army. I n a l i t t l e l e s s than two years he completed a t y p i c a l l y f o u r year task of a c h i e v i n g h i s doctorate with Wilhelm Schlenk, summa cum laude i n 1921, while simultaneously c o u r t i n g a t a l l , blond young woman named Maria Schramek, who became i n 1922 Mrs. Herman F r a n c i s Mark. He was i n s t r u c t o r at the U n i v e r s i t y of B e r l i n i n 1921 and one year l a t e r j o i n e d the K a i s e r Wilhelm I n s t i t u t f u e r F a s e r s t a f f - c h e m i e i n Berlin-Dahlem. During t h i s time he met and became f r i e n d s with von Laue who had discovered that when a narrow beam of X-rays was passed through a c r y s t a l l i n e m a t e r i a l , geometric p a t t e r n s formed on the X-ray f i l m s . His f i r s t two of w e l l over 600 p u b l i c a t i o n s appeared i n 1922 i n B e r i c h t e der Deutschen Chemischen G e s e l l s c h a f t on "Nature of the Carbon Bond", "Free Pentaphenylethyl" and "Analogs of Pentaphenylethyl", both coauthored with Schlenk.

In 1923 one of Mark's s u p e r i o r s handed him a piece of hemp and asked that he study i t s molecular s t r u c t u r e . Hemp was one of the many n a t u r a l m a t e r i a l s we now recognize as macromolecules which to then d e f i e d s t r u c t u r a l a n a l y s i s . A f t e r much thought and work, a l s o i n c l u d i n g X-ray s t u d i e s , he concluded that the hemp f i b e r contained c r y s t a l s . On examination, so a l s o d i d cotton, wood and flax. The acceptance of macromolecules was s t i l l h o t l y debated even though the work of Hermann Staudinger i n the 1910*s and the 1920's showed, a t l e a s t to some, that macromolecules d i d indeed e x i s t . Gradually Mark and h i s colleagues determined that the c e l l u ­ l o s e molecules were, i n f a c t , long chains of thousands of atoms making up hundreds of glucose u n i t s connected to form s i n g l e p o l y ­ meric molecules of c e l l u l o s e . The s i g n i f i c a n c e of t h i s work i s not to be overlooked. T h i s was one of only a few b a s i c cornerstones upon which the g i a n t of polymer science now r e s t s . In January 1927, the Marks were l u r e d by Kurt Meyer, d i r e c t o r of research f o r I . G. Farben, to be both a p r o f e s s o r and head of a l a b o r a t o r y s t a f f e d by 20 s c i e n t i s t s . He became a h i g h l y popular l e c t u r e r throughout Europe. While t h i s p o p u l a r i t y d e l i g h t e d Farben d i r e c t o r s , h i s research e f f o r t s had not f i l l e d the com­ pany's t i l l s . Within Mark's mind were p i c t u r e s of branched, e l o n ­ gated, "zig-zagged", i n t e r l o c k e d c h a i r s and the p e r s i s t e n t taunt­ ing regarding p r o p e r t y - s t r u c t u r e r e l a t i o n s h i p s . During t h i s time, p u b l i c a t i o n number 50 came f o r t h , h i s f i r s t book "Die Verwendung der Roentgenstrahlen i n Chemie und Technik" was published. According to Maurice Huggins, "Mark c o n t r i b u t e d importantly to my own education ( i n X-ray science and i n the German language) i n the mid-1920's through t h i s e x c e l l e n t book". Thus, Mark began e a r l y to c o n t r i b u t e w i t h i n a l l three areas of polymer education-teaching, research and s e r v i c e , the l a t t e r i n c l u d i n g p u b l i c a t i o n of s i g n i f i c a n t works. Using i n s i g h t s c o n t r i b u t e d to by Mark, h i s l a b o r a t o r y group was s t e a d i l y concocting new polymers, t u r n i n g them over to the development department. Toward the end of 1929, word was rushed about the p l a n t that one of these showed great promise. This polymer was formed from the common l i q u i d styrene and could be transformed i n t o a c l e a r p l a s t i c from which c i g a r holders, toys, handles, e t c . could be constructed. About a month l a t e r the f i r s t order f o r polystyrene was placed. The c r i s i s was past. During the next f o u r years many a d d i t i o n a l new polymers were synthesized. Most proved of l i t t l e commercial value, but the l i s t i n c l u d e s three of the top-ranked popular p l a s t i c f a m i l i e s - the p o l y v i n y l s used f o r phonograph records and f l o o r t i l e s ; polya c r y l i c s (such as L u c i t e ) used i n p a i n t s , a i r p l a n e windows and buna Ν and buna S, two v e r s i o n s of s y n t h e t i c rubber. Thus few households are not a f f e c t e d by even h i s e a r l y c o n t r i b u t i o n s . In October of 1932 the Mark f a m i l y , which now i n c l u d e d Hans, then three, and Peter, then s i x months o l d , returned to Vienna to

He a l s o discovered that the g l a c i e r s contained higher percentages o f D^O than d i d newly-formed i c e . In March 1938 he was a r r e s t e d by the Gestapo and, a f t e r a n i g h t o f q u e s t i o n i n g , f r e e d without h i s passport.

The higher a d m i n i s t r a t i o n was probably aware of the goings-on from the beginning, but by 1 9 4 5 P r e s i d e n t Harry Rogers summoned Mark and Frankuchen i n t o h i s o f f i c e to d i s c u s s t h i s venture. They t a l k e d of the t r a v e l i n g fund o p e r a t i o n and Rogers warmed to the idea. He not only encouraged f u r t h e r development of the operat i o n , but r e l i e v e d them of the r o u t i n e d e t a i l s i n c i d e n t to operat i o n of the summer program, making i t a part of the normal Univers i t y operation. During t h i s time the developing team of polymer s c i e n t i s t s at "Brooklyn Poly" began g i v i n g weekly seminars which a t t r a c t e d i n d u s t r i a l and academic chemists from the surrounding g r e a t e r New York C i t y M e t r o p o l i t a n area. The l e c t u r e s were given by graduate students, f a c u l t y and v i s i t i n g s c i e n t i s t s from many d i f f e r e n t coun t r i e s . The Saturday seminars were a welcome change of pace s i n c e , because of the war e f f o r t , most chemists had to work on Saturdays with the seminars being a recognized l e g i t i m a t e a l t e r n a t i v e by the i n d u s t r i a l s u p e r i o r s . A l s o they were f r e e and " a f t e r speech" interchanges were encouraged. A Thursday n i g h t s e r i e s a l s o emerged. Thus the c r i t i c a l bridge between academics and i n d u s t r y was being b u i l t - a bridge which has continued to grow but which i s c u r r e n t l y i n great need of r e p a i r and e n l a r g i n g to support the needed ongoing r e v i t a l i z a t i o n i n the growth of polymer s c i ence. Mark was a l s o proving to be q u i t e a magnet as an academic research a d v i s e r , adding f i v e p r o f e s s o r s and 6 0 graduate students to the P o l y t e c h f o l d . To Mark, i t became p l a i n that the polymer a c t i v i t y a t Brookl y n Poly needed to be h i g h l i g h t e d to gain the support and r e c o g n i t i o n i t deserved. T h i s time he approached P r e s i d e n t Rogers with his plan. On paper the establishment of an i n s t i t u t e to study polymers would cost about two hundred thousand d o l l a r s annually, but Mark eagerly contended that the s t a f f , equipment, e t c . were already present so the " s t a r t up" c o s t s would be l i m i t e d to orderi n g new l e t t e r h e a d s . Rogers was reported to have muttered f o r s e v e r a l days, a t i n t e r v a l s , "Genius! Sheer genius!" Thus the Polymer Research I n s t i t u t e o f f i c i a l l y came i n t o being with the p r i n t i n g of the l e t t e r h e a d s . Along with the need to "spread the news" of polymer s c i e n c e was the i n c r e a s i n g need to develop an adequate v e h i c l e which would focus on the dissemination of generated experimental r e s u l t s i n polymer chemistry.

I t has subdivided many times and " f a t h e r e d " such J o u r n a l s as the J o u r n a l of A p p l i e d Polymer Science and Polymer L e t t e r s .

Carothers, as d i r e c t o r o f Du Pont*s polymer research. The work a s s o c i a t e d with Mark and Carothers s i g n a l e d the break from the e m p i r i c a l p r a c t i c e o f polymer chemist r y and the b i r t h o f the s c i e n c e o f polymers. Carothers d i r e c t e d the research group which on October 27, 1938 p u b l i c l y announced the s y n t h e s i s o f a s y n t h e t i c polymer which, f o r the f i r s t time i n h i s t o r y , had p r o p e r t i e s s u p e r i o r t o n a t u r a l f i b e r s . The polymer was nylon. The science of polymer chemistry was born, an i n f a n t , when most of i t s brother and s i s t e r s c i e n t i f i c d i s c i p l i n e s were a l r e a d y adults. The beginnings o f academic polymer education i n the USA are unclear a t best because, as with most s c i e n c e s , polymer chemistry emerged, grew from a number o f s c i e n c e s - s c i e n c e and a r t a s s o c i a t ed with f a b r i c s and t e x t i l e s (making o f boat s a i l s , sheets, c l o t h ing), c o a t i n g s ( o i l based), adhesives ( r o s i n s , glues) and rubbers. For i n s t a n c e a course i n p a i n t technology was s t a r t e d i n 1906 a t North Dakota S t a t e U n i v e r s i t y . Other courses i n t e x t i l e s , coatings and c e l l u l o s i c m a t e r i a l s were a l s o being taught p r i o r t o 1920.

Considerable subject matter now termed polymer chemistry was contained i n a course designated as " C o l l o i d Chemistry" a t the U n i v e r s i t y o f Delaware by E.O.

The e a r l y focus of polymer r e l a t e d education was then a l s o largely empirical. The f i r s t formal course i n polymer chemistry which balanced theory with p r a c t i c e was probably one a s s o c i a t e d with Herman Mark given at the P o l y t e c h n i c s h o r t l y a f t e r h i s a r r i val. Ray Seymour o f f e r e d such a course at the U n i v e r s i t y of Chattanooga i n 1945. By the middle 1940's the P o l y t e c h n i c had a t t r a c t e d a number of outstanding "polymer" chemists (Herbert Morawitz, Turner A l f r e y , Paul Doty, Bruno Zimm, Kurt S t e r n , A. McLaren, Fred E i r i c h and Charles Overberger) under the d i r e c t o r s h i p of Herman Mark. A program of graduate study l e a d i n g to a M.S. and Ph.D. degree with a major i n polymer chemistry was developed, undoubtedly the f i r s t such program i n the USA. Course o f f e r i n g s were: I n t r o d u c t i o n o f Polymer Chemistry (Mark) Polymerization K i n e t i c s (Alfrey) S o l u t i o n P r o p e r t i e s of High Polymers ( E i r i c h ) Organic Polymer Chemistry (Overberger) and Chemistry of P r o t e i n s (McLaren) Compared to more c l a s s i c a l areas of chemistry there was l i t t l e formal education and academic based research r e l a t e d to p o l y mer chemistry through the l a t e 1950 s although there e x i s t e d a small number of i n d i v i d u a l s and groups who were conducting important p i o n e e r i n g work i n c l u d i n g C a r l Marvel and F.T.

Industry, seeing a need f o r t r a i n i n g those employed by them i n the a r t and s c i e n c e of polymer chemistry, began to experiment.

The American Chemical S o c i e t y has had a great deal to do with f o s t e r i n g polymer education through s e v e r a l of i t s D i v i s i o n s and the J o u r n a l of Chemical Education. In 1919 the D i v i s i o n of Rubber Chemistry (then c l a s s i f i e d as a S e c t i o n ) was organized as the ACS s n i n t h D i v i s i o n . In the e a r l y 1920's the S c i e n t i f i c S e c t i o n of the Paint Manufacturers of the United S t a t e s and the N a t i o n a l V a r n i s h Manufacturers A s s o c i a t i o n provided the impetus f o r b r i n g ing p a i n t chemists together to d i s c u s s mutual problems and to provide a forum where papers could be presented and d i s c u s s e d . The f i r s t of these meetings occurred i n June 1922 i n Washington, D.C. and was organized by Henry Gardner. A f t e r a second meeting (1923) the subject of a f f i l i a t i o n with the ACS was considered with H.A. Gardner appointed as a committee of one to confer with ACS o f f i c e r s . On October 20, 1923, W.T. Pearce sent to the ACS S e c r e t a r y Parsons a p e t i t i o n with about 100 s i g n a t u r e s .

Through 1959 there e x i s t e d only one l a r g e c o n c e n t r a t i o n of polymer chemists i n academia (at the P o l y t e c h n i c I n s t i t u t e o f Brooklyn) with s e v e r a l smaller academic centers f e a t u r i n g concent r a t i o n s i n t e x t i l e s , c e l l u l o s e s and wood, rubber and c o a t i n g s . S e r i e s of short courses, seminars, j o u r n a l s , monograms and t e x t books had been e s t a b l i s h e d and were to grow through the 60 s to the present. The I960 s saw an i n c r e a s e i n the number of f o r m a l l y d e s i g nated polymer or macromolecular i n s t i t u t i o n s .

"Brooklyn Poly", the center of academic polymer chemistry i n the USA i n the 1940 s and 1950's remained as such but became l e s s dominant because a number of t h e i r e x c e l l e n t s t a f f l e f t to found other i n s t i t u t e s . For i n s t a n c e , Charles Overberger, who rose to Dean of Science and D i r e c t o r of the Polymer Research I n s t i t u t e , l e f t i n 1967 to take the chairmanship of the Department of Chemistry a t the U n i v e r s i t y of Michigan where he helped found t h e i r macromolecular based i n s t i t u t e . The beginning of the 1970 s saw a c o n t i n u a t i o n of the academic apathy towards formal t r a i n i n g i n polymers which marked the 1950 s and 1960 s. T h i s t o p i c was h o t l y debated by ACS p r e s i d e n t s at ACS meetings ( f o r i n s t a n c e 1-3), w i t h i n workshops ( f o r i n s t a n c e 4) and w i t h i n the inner c i r c l e of the ACS ( f o r instance 5 ) . S t i l l s i g n i f i c a n t steps towards a c t u a l l y a c h i e v i n g advances i n the f o r mal i n c l u s i o n of polymers i n the academic t r a i n i n g of chemists had to wait f o r a beginning u n t i l 1974. In summary, the p e r i o d from the 1940 s through 1973 saw a steady, healthy i n c r e a s e i n postgraduate education spearheaded by academics, i n d u s t r y and government and a slower, steady i n c r e a s e i n the number of schools o f f e r i n g graduate education i n polymer chemistry, but the l a t t e r was c l e a r l y undernourished i n comparison with the r e l a t i v e importance o f polymer chemistry i n i n d u s t r y .

Recognition - 1974 t o Present While previous ACS p r e s i d e n t s had c a l l e d f o r g r e a t e r emphasis i n the academic t r a i n i n g o f chemists, i t was during W i l l i a m B a i l e y ' s presidency that the c a l l was heeded. S i g n i f i c a n t inner committee assignments were being f i l l e d by those sympathetic with the cause. Further, the Polymer D i v i s i o n ' s Education and P u b l i c R e l a t i o n s Committees were primed f o r a c t i o n . The formulation o f an o v e r a l l plan to achieve the needed g r e a t e r emphasis o f polymer education was begun a t a meeting a t A t l a n t i c C i t y o f the ACS i n 1974 a t the d i r e c t i o n o f E l i Pearce and Joe Salamone who c a l l e d myself and others under the auspices o f the D i v i s i o n o f Polymer Chemistry's Committees on Education and P u b l i c R e l a t i o n s . I t was agreed that not only was graduate education i n polymer chemistry l a c k i n g the emphasis i t deserved and that p r e v i ous attempts aimed a t i n c r e a s i n g the emphasis o f polymers i n graduate education had r e c e i v e d only minimal success, but t h a t there was almost no emphasis on undergraduate education r e l a t e d t o polymer chemistry. Rather than r e p e a t i n g the same programs that had r e c e i v e d minimal success aimed a t graduate education, we were convinced that the s o l u t i o n to the problem o f polymer education throughout the e d u c a t i o n a l l e v e l s would b e t t e r be solved i f we focused our e f f o r t s on undergraduate education which would r e s u l t i n a much e a s i e r upward flow o f i n t e r e s t i n polymer chemistry i f we were s u c c e s s f u l a t the undergraduate l e v e l . F u r t h e r , we r e a l i z e d that we needed a l a r g e - s c a l e , w e l l - o r c h e s t r a t e d approach with the cooperation o f a l l o f the sub-polymer d i s c i p l i n e s and t h e i r many members. That week I contacted Lieng-Huang (Sam) Lee, C l a r a Carver and George Brewer concerning our proposed emphasis. T h e i r support was q u i t e p o s i t i v e asking me to serve as Education L i a i s o n and to compose an Education Committee f o r the D i v i s i o n o f Organic Coatings and P l a s t i c s Chemistry. Of note was (and continues to be) the e f f o r t s o f the J o i n t Education Committees of the D i v i s i o n s o f Polymer Chemistry (chaired by E l i Pearce; p r e s e n t l y c h a i r e d by Guy Donaruma) and Organic Coatings and P l a s t i c s Chemistry ( c h a i r e d by Charles C a r r a h e r ) . Most o f the accomplishments noted f o l l o w i n g c o u l d not have been accomplished without the j o i n t cooperation o f these two committees which acted as one "super" committee. The p e r i o d between the A t l a n t i c C i t y meeting and the P h i l a d e l p h i a meeting was very a c t i v e and d i r e c t i o n s f o r a c h i e v i n g our goal were cemented. The major steps were (a) p r e l i m i n a r y i n v e s t i g a t i o n aimed a t o b t a i n i n g NSF support f o r summer short courses i n polymer chemistry f o r c o l l e g e teachers o f undergraduate g e n e r a l , organic, a n a l y t i c a l and p h y s i c a l chemistry; (b) generation o f a l a b o r a t o r y manual f o r use i n undergraduate courses o f g e n e r a l ,

T h i s was submitted to the NSF Education O f f i c e of Experimental P r o j e c t s and Programs i n November of 1974. Papers were a l s o prepared and presented to members of the ACS Committee on P r o f e s s i o n a l T r a i n i n g and the Committee on Education. During t h i s time, B i l l B a i l e y and others were a c t i v e i n our support. In December 1974, we r e c e i v e d from NSF a request f o r a formal p r o p o s a l . The C o u n c i l Committee on Chemical Education went on r e c o r d a t the P h i l a d e l p h i a meeting f a v o r i n g g r e a t e r emphasis of polymer chemistry i n the undergraduate t r a i n i n g of chemists. Through the e f f o r t s of many, the Committee on P r o f e s s i o n a l T r a i n i n g voted to i n c l u d e a course i n polymer chemistry i n the ACS approved major i n the 1978 p u b l i c a t i o n . T h i s t o p i c w i l l be considered l a t e r i n greater d e t a i l . At the P h i l a d e l p h i a meeting, Ray Seymour and I met with the ACS Examination's Committee. We were asked to generate answers to a number of questions i n p r e p a r a t i o n f o r a d e c i s i o n by them to support or not support an ACS standardized t e s t i n polymer chemistry. To gather i n f o r m a t i o n needed f o r t h i s and other p r o j e c t s , Rudy Deanin surveyed over 110 departments o f f e r i n g courses i n polymer chemistry a s s e s s i n g the p o t e n t i a l need and use of a s t a n dardized t e s t i n polymer chemistry and e v a l u a t i n g t o p i c s which should be i n c l u d e d w i t h i n an i n t r o d u c t o r y polymer course. Shalaby Shalaby and E l i Pearce were asked to e d i t an i s s u e of CHEMISTRY devoted to polymer chemistry. During t h i s time the f i r s t ACS I n t e r a c t i o n S e r i e s - "Polymer Science and Technology - An I n t e r d i s c i p l i n a r y Approach" - under the d i r e c t i o n of E l i Pearce, Shalaby Shalaby and Garth Wilkes was under p r e p a r a t i o n .

monality of d e s i r e d course content f o r an i n t r o d u c t o r y course i n polymer chemistry, something that was hoped f o r but something that was not known. The Ninth B i e n n i a l Education Conference of the ACS met on October 16-18, 1975 and s t r o n g l y endorsed the need f o r i n c r e a s e d emphasis of polymer education. At the ACS meeting i n New York C i t y , two p r e t e s t s were cons t r u c t e d f o r use. This was done with the considerable help of Charles Gebelein, Les S p e r l i n g and Angelo Volpe u t i l i z i n g Deanin's survey of t o p i c s as a guide. The ACS, through the a c t i v e support of the D i v i s i o n s of Polymer Chemistry and Organic Coatings and P l a s t i c s Chemistry, helped i n the generation of t h i s examination. Over 60 c o n t r i b u t o r s from schools and i n d u s t r y d i r e c t l y helped i n such areas as p r e t e s t i n g and submission o f questions. Thus, the generation of the f i r s t ACS Standardized Examination i n polymer chemistry was accomplished with help from a wide base. The examin a t i o n has s o l d about 2,000 copies during the f i r s t year s i n c e i t s p u b l i c a t i o n i n 1978. Considerable i n t e r e s t has been shown by chemical s o c i e t i e s from other nations i n the examination and the ACS Committee on Examinations i s c u r r e n t l y c o n s i d e r i n g p e r m i t t i n g i t s use outside of the USA. This examination should a s s i s t i n generating a d d i t i o n a l commonality i n i n t r o d u c t o r y courses. Some d i v e r s i t y i s important to r e f l e c t the breadth of polymer science t e x t i l e s , n a t u r a l m a t e r i a l s , rubbers, p l a s t i c s , m a t e r i a l s e n g i neering and processing, e t c . Thus, while there i s an aim towards s t a n d a r d i z a t i o n o f content and t o p i c s , i t i s g e n e r a l l y accepted that the amount of t h i s " s t a n d a r d i z a t i o n " should only be i n the 70? to 80% range. The NSF proposed Short Course i n Polymer Chemistry died a death of o l d age s i n c e by the time i t emerged from CEPACC i n 1977, the climate at NSF had changed so that teacher r e t r a i n i n g programs were no longer i n f a s h i o n even though a strong case was made that t h i s was of such a strong need and of s u f f i c i e n t worth to the USA that an exception should be made.

Two short courses on Polymer C r y s t a l l i n i t y and Rubber E l a s t i c i t y w i l l be o f f e r e d at the New York ACS i n 1981. The short course on Rubber E l a s t i c i t y w i l l be held j u s t p r i o r to a symposium covering the same t o p i c . T h i s i s d i r e c t e d by Frank H a r r i s and i s f r e e .

The survey showed a s u r p r i s i n g l y s t r o n g trend toward the f e e l i n g that more polymer science should be i n cluded i n the academic t r a i n i n g of chemists and chemical e n g i neers. Twenty courses were l i s t e d on the o r i g i n a l survey along with the category "other". E s s e n t i a l l y a l l the respondents (59 out of 60) recommended that students should take a general course i n polymer chemistry. Six of the top seven top rated courses d e a l t with polymers (Polymer Laboratory - 72%; Polymer Processing - 72%; Engineering Polymers - 60%) with only Advanced Organic (63%) breaking i n t o the top 5.

An updating of the Salamone, Deanin, Young and Pearce 1972(6) survey to determine trends with academics regarding polymer t r a i n ing has r e c e n t l y been completed under Rudy Deanin. The previous study showed about 110 schools o f f e r i n g some polymer s c i e n c e . The recent survey shows about 135 now o f f e r i n g polymer science, an i n c r e a s e o f about 25% over e i g h t years. Further, the trend towards o f f e r i n g polymer s c i e n c e has g r e a t l y i n c r e a s e d s i n c e 1978 and i t i s expected that a doubling to about 350 schools w i l l occur by 1985.

uses by academic and i n d u s t r i a l o r g a n i z a t i o n s f o r d i s t r i b u t i o n to youth and the general p u b l i c . Two n a t i o n a l ACS r e l a t e d symposia with polymer education were conducted i n 1979. Both were co-chaired by E l i Pearce and Charles Carraher. The f i r s t occurred during the Hawaii ACS meeting and was i n i t i a t e d a t the i n v i t a t i o n o f Robert Brasted on behalf o f the D i v i s i o n o f Chemical Education and j o i n t l y sponsored by the D i v i sions o f Organic Coatings and P l a s t i c s Chemistry and Polymer Chemistry. T o p i c s were centered about helps and i n t r o d u c t o r y course contents. The second symposium occurred a t the Washington, D.C. meeting co-sponsored by the same three D i v i s i o n s . T h i s was a f u l l symposium with about 20 t a l k s given v a r y i n g from how t o i n t r o duce polymer t o p i c s i n t o undergraduate courses o f i n o r g a n i c , organ i c and p h y s i c a l chemistry, to those n o t i n g the importance o f polymers to s o c i e t y and to the proper education o f chemists and to s p e c i a l p r o j e c t s r e l a t e d t o polymer education. A summer s c h o l a r s h i p program has begun under the sponsorship of P r o c t o r & Gamble. The program r e s u l t e d i n about 500 i n q u i r i e s with e v e n t u a l l y s i x summer s c h o l a r s h i p s awarded to support work on polymer r e l a t e d research p r o j e c t s . F l y e r s were mailed t o about 1200 departments o f chemistry. Such propagation i s worthwhile i n a d v e r t i s i n g the prospects that await those who d e s i r e t o enter i n d u s t r y i n polymer-related ventures. I t i s hoped that t h i s program w i l l grow. S e v e r a l awards r e l a t e d to polymer education are i n the "wings". Thus the present a c t i v i t y w i t h i n the v a r i o u s polymer educat i o n committees i s broad, f a r - r e a c h i n g , t i m e l y and p r o g r e s s i v e . In summary, the 1970 s began with the same academic p a s s i v e ness toward polymer education that marked the 1950 s and 1960's, but i n 1974 major developments aimed a t the g r e a t e r i n c l u s i o n o f polymer chemistry i n t o the c u r r i c u l u m o f chemists began and f o r the f i r s t time emphasized the undergraduate t r a i n i n g o f chemists. The most s i g n i f i c a n t s i n g l e event was the ACS pronouncement that aspects o f polymer chemistry were to be core m a t e r i a l i n the t r a i n ing o f ACS a c c r e d i t e d chemistry majors. 1

We must continue to be a c t i v e a t promoting the g r e a t e r i n c l u s i o n o f polymer t o p i c s , i l l u s t r a t i o n s and concepts i n t o the formal education o f our chemists and chemical engineers not j u s t because we are polymer chemists but because i t i s c r i t i c a l to the growth o f our i n d u s t r i e s , our nation, as w e l l as many r e l a t e d branches o f s c i e n c e , h e a l t h and technology. The Geheimrat continues to be a c t i v e i n a l l the aspects o f an educator - teaching, s e r v i c e and r e s e a r c h . He has been a constant source o f help and support during the present p e r i o d , working behind the scenes i n our behalf, counseling and prodding.

POLYMER SCIENCE

OVERVIEW

Polymer education has grown from a seed a t "Brooklyn Poly" t o a young g i a n t redwood which i s t a k i n g i t s r i g h t f u l p l a c e as a g i a n t among g i a n t s . T h i s growth has been c a t a l y z e d by the Geheimrat, not only from h i s ivy-covered w a l l s i n Brooklyn, but from a constant preaching, as a possessed e v a n g e l i s t o f the "polymer g o s p e l " a t almost any school or i n s t i t u t i o n which would i n v i t e him. I n the e a r l i e r years he would a r r i v e by bus, d e l i v e r h i s message o f "hope and l i g h t " and a f t e r an a p p r o p r i a t e v i s i t a t i o n with those present, leave - h i s apppearance c o s t i n g no more than bus f a r e . H i s g u i d ance continues as he continues h i s "camp meetings" t r y i n g to "save the l o s t " and "comfort the saved" o f t e n speaking o f f u t u r e needs, f u t u r e s o l u t i o n s - the f u t u r e - indeed a man f o r ALL seasons. A teacher, servant o f mankind, e d i t o r , chemist, student, f a t h e r , husband, author, a d m i n i s t r a t o r , o r g a n i z e r - a f u t u r i s t , helper and friend. We thank you f o r your help, guidance

and f r i e n d s h i p .
