hibited at t h e National Plastics E x p o sition mark American Cvanainid's entry into t h e thermoplastics field. C y m a c 400 is a n injection molding c o m p o u n d based o n methylstyrene and C y m a c 201 is based on methylstyreneacrylonitrile copolymer. Both m a y b e molded in any equipment designed for use with regular p o h s t y r e n e . Cymac· 400 is said t o have u n u s u a l heat resistance, showing no a p p a r e n t distortion after repeated e x t e n d e d ex posures at 212° F. Additionally, t h e company says it possesses all o t h e r d e sirable properties of polystyrene includ ing excellent color, clarity, and electri cal properties. Its chemical resistance is stated to be a s good a s that of poly styrene. It is stated t o b e especially useful for molding parts requiring serv ice at relatively high t e m p e r a t u r e s , such as exposure to boiling w a t e r . C y m a c 400 will b e offered in crystal, Bureau of Standards colors, a n d special colors. The properties of C y m a c 4 0 0 fît it for use in such applications a s radio cabinets, industrial battery cases, housewares, tableware, wall tile, b r u s h backs, refrigerator p a r t s , c o u n t e r w a r e , phonograph records, decorative lighting, small appliance housings, stove and washing machine parts, hospital and medical apparatus, a n d p a c k a g i n g . Moldings made from C y m a c 2 0 1 possess a u n i q u e combination of p r o p erties n o t found in' o t h e r molding compounds, according t o American C y a n a mid. T h e s e include toughness a n d r e sistance to heat, crazing, chemicals, a n d surface marring. It, too, is said t o h a v e excellent clarity. Regarding its chemical resistance, company says it is even better than that of C y m a c 4 0 0 . I t resists attack b y materials such a s aliphatic hydrocarbons, gasoline, essential oils, vegetable and mineral oils. It is especially suited for molding a r o u n d metal inserts. Company will m a n u f a c ture Cymac 201 in natural, ice t i n t , a n d a wide range of colors. T h e company lists possible applications for C y m a c 2 0 1 t o include radio cabinets, housewares, tableware, institutional dinnerware, brush backs, r e -
frigerator parts, business machine housings, packaging, counterware, a p pliance housings, stove a n d washing machine parts, electrical fan blades, industrial battery cases, a n d communications e q u i p m e n t . T h e n e w molding compounds are being p r o d u c e d a t American Cvanainid's Wallingford, Conn., plant. They are currently offered in one* standard pellet size intended primarily for injection molding. Both will b e shipped in SO-pound multiwall paper bags a n d 200-pound Leverpak type drums. They are priced competitively with general purpose polystyrene. C 1
Kojic Acid Derivatives Research quantities of t w o kojic acid derivatives, chlorokojic acid a n d kojyl palmitate, are offered by Chas. Pfizer's chemical sales division. Chlorokojic acid (2-chloromethyl-5hydmw-gamma-pyrone) is a stable intermediate w h i c h can be used as a route t o compounds not formed directly from t h e parent kojic acid. These include such possibilities as pharmaceuticals, dyestuffs, insecticides, and antifungal and antimicrobial agents, company says. T h e fungicidal properties of certain metal chelates of chlorokojic acid suggest their use in agricultural disease control, as mildewcides a n d fungicides in paints, water treatment, paper processing, a n d textile finishing. Kojyl palmitate ( 2-palmitoxymethyl5-hydroxy-ga?nr?ia-pyrone) is said to h a v e potential uses in removal of trace metals from nonaqueous media, such as petroleum oils a n d paint additives. Chelating properties in such systems are retained b y compound. C2
Calcium Arsenate Spray Calcium arsenate which can b e applied a s a low gallonage spray instead of a dust has been developed b y Allied" Chemical & Dye's general chemical division. T h e n e w spray form is said to be less wasteful, t o give longer residual
effect and better insert control and also t o eliminate hazards of drifting arsen ical dust. T h e n e w formuk&'tion will b e sold u n d e r name of General Chemical High Suspension Calciunii Arsenate. It is said t o mix well in « t h e r hard or soft water. A spray mbcture containing 1 p o u n d of compound fuer gallon is said to give effective weevil control w h e n a p plied at rate of fromm 7 t o 10 gallons per acre. C3
