m CAN ALPHA'S DiFFEREN MAKE A DIFFERENCE FOR YOU? New monomer now available for evaluation Now produced commercially by Hercules at its new oxychemicals plant at Gibbstown, New Jersey, alphamethylstyrene provides a challenge to chemists who are looking for a lower priced material with many of styrene's advantages plus numerous unique properties of its own. Hercules αΖρ/ια-methylstyrene is an unsaturated hydrocarbon, derived from propylene and benzene, that boils at about 165°C. It eopolymerizes with other monomers such as sty­ rene, butadiene, divinylbenzene, and

acrylonitrile. Alpha-met îylstyrene does not polymerize alone readily by a free radical mechanism. This results in increased storage stability. It can, however, serve as a reaction modifier when used as a partial replacement for styrene in many of the latter's uses. Such uses include GR-S rubber, s t y r e n e - b u t a d i e n e latices, styrenated drying oils,

styrenated alkyds, and polyesters. Low molecular weight polymers of αφΑα-methylstyrene have been found useful as low-cost plasticizers for such items as hot-melt resins and wire coating. Hercules will be glad to send you a generous sample for testing, and subsequently to cooperate with you in working on specific applications.
