It eopolymer-izes with other monomers such as styrene, butadiene, divinylbenzene, and </p><p>acrylonitrile. Alpha-met ylstyrene does not polymerize alone readily by a free radical mechanism. This results in increased storage stability. </p><p>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, </p><p>styrenated alkyds, and polyesters. Low molecular weight polymers </p><p>of -methylstyrene have been found useful as low-cost plasticizers for such items as hot-melt resins and wire coating. </p><p>Hercules will be glad to send you a generous sample for testing, and subsequently to cooperate with you in working on specific applications. </p><p>Oxychemicals Division, Naval Stores Department HERCULES POWDER COMPANY </p><p>932 Market St., Wilmington 99, Del. * </p><p>J A N . 9, 1956 C &amp; E N 1 2 1 </p><p>0Jc4M^^/vn&amp;^^ </p><p>^UnmfL I p ^ v t </p><p>r"_ </p><p>m </p><p>CAN ALPHA'S DIFFERENCE MAKE A DIFFERENCE FOR YOU?</p></li></ul>
