    CAN ALPHA'S DiFFEREN MAKE A DIFFERENCE FOR YOU?

    New monomer now available for evaluation

    Now produced commercially by Her-cules at its new oxychemicals plant at Gibbstown, New Jersey, alpha-methylstyrene 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 /-methylstyrene is an unsaturated hydrocarbon, derived from propylene and benzene, that boils at about 165C. It eopolymer-izes with other monomers such as styrene, butadiene, divinylbenzene, and

    acrylonitrile. Alpha-met ylstyrene does not polymerize alone readily by a free radical mechanism. This results in increased storage stability.

    It can, however, serve as a reac-tion modifier when used as a partial replacement for styrene in many of the latter's uses. Such uses include GR-S rubber, s ty rene-bu tad iene la t ices , s tyrenated drying oils,

    styrenated alkyds, and polyesters. Low molecular weight polymers

    of -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.
