enough from this mold to justify its cost before the piece (housing) is obsoleted by technological developments and style trends." Shortage of Polystyrene Injection molders were present in force and also were up in arms over the threat to their industry of the shortage of polyst> rene. This thermoplastic, derived from benzene, has been in great demand, but unfortunately the molders have been forced to take a back seat by the steppedup synthetic rubber program. The im portance of various thermoplastics for mili tary applications was brought out by Stan ley R. Melvin of Monsanto Chemical Co. who spoke on postmolding treatment. He also stated that the Armed Forces' pro curement agencies are investigating or pur chasing plastics. Utility, durability, and eye appeal are greatly enhanced by such processes as dec orating, assembly, metal-plating, finish ing, and other postmolding techniques, said Melvin. Decorating, for example, in cludes lacquering, silk screening, hot stamping, printing, application of decal-
comanias, and the like. Metalizing—the process of applying a thin film of metal in order to protect the plastic against scratching, solvents, and dust—may be per formed by electroplating, spray-plating, vacuum coating, and cathode sputtering. Melvin concluded that "a firm's ability to manufacture useful and beautiful plas tic articles need not stop when the die platen opens." Postmolding techniques offer a number of versatile operations for product improvement. Rigid Plastics Robert Burns of Bell Telephone Labo ratories, Inc., discussed properties of rigid plastics, particularly cold flow, stress re lease, maximum service temperature, crazing and cracking, and unusual elec trical properties. Burns believed that proper use of data sheets provides the de sign engineer with a sound mechanism for plastics application. Compression molding of glass reinforced plastics was treated by Clare E. Bacon of Owens-Corning Fiberglas Corp. with par ticular reference to physical properties and applications.

C&EN REPORTS: Association of Consulting Chemists and Chemical Engineers
NEW YORK.-The consultant must act now to tell his story to the chemical in dustry and the general public, according to Paul Slawter of the House of J. Hayden Twiss, featured speaker of the consultant's annual meeting on Oct. 24. The ACS News Service is telling the chemist's and chemical engineer's part in the growth of chemistry and the Manufacturing Chem ists' Association is inaugurating a program to publicize the industries' part in the de velopment of the chemical age. So far no one is telling the consultant's part accord ing to the speaker. Slawter told the consultants that they must "get the alchemy out of your public relations program." He said that few people in the chemical industries know the names of more than a few consultants much less the nature of their specialties. To remedy this situation he recommended that the consultants take their story aggres sively to their "publics," "not with oneinch professional cards . . . but with real honest-to-goodness full page advertise ments, signed by the association . . ." Such a program would require greater co operation among the individual consultants, however. Slawter told them, "You quarrel among yourselves instead of working for the good of your profession . . . You en gage in petty jealousies that would dis credit a schoolgirl, expending energies that V O L U M E

might well be used to enhance your stand ing in the field." In the discussion period that followed the presentation many questions were raised as to the mechanism for implement ing a program such as that suggested by Mr. Slawter. There seemed to be no readily apparent source for the money that such an undertaking would require. How ever, the majority of the members present and the officers of the association agreed that an expanded public relations pro gram should be taken under consideration and the newly appointed president, Ermin Di Cyan of Di Cyan and Brown promised that the suggestions made at the open meeting would be discussed at the next meeting of the executive board. In addition to Dr. Di Cyan the new officers installed at the annual meeting were: Earl D. Stewart of Schwarz Labora tories, vice president; Robert S. Aries of R. S. Aries and Associates, treasurer; and Albert Parsons Sachs, independent con sultant, secretary. Charles L. Mantell, Nicholas M. Molnar, Maurice S. Sage, Frank A. Strauss, and Lincoln T. Work were the newly elected councilors. Copies of the proceedings of the meet ing including the discussion of Mr. Slawter's paper may be obtained from the offices of the association, 50 E. 41st St., New York, Ν. Υ., for $1.00.
