    • Di(vinylaryl)alkyl polysulfides and curable, low odor (vinylaryl)alkyl-terminated polysulfide copolymers having the general structure ##STR1## wherein n is an integer from about 2 to about 8, 1 and m are positive integers, each R is independently an organic polyradical with the radicals residing on carbon atoms, p is zero or a positive integer which is the difference between the number of radicals on R and 2, and each Z is independently chosen from the class consisting of (vinylaryl)alkyl and other noncrosslinking monoradicals, provided that a sufficient proportion of the Z groups are (vinylaryl)alkyl that the polymer, when cured, does not cold flow. Additionally, a method of preparing said polymers and useful adhesive, sealant and caulking compositions made therefrom are disclosed.
    • 二(乙烯基芳基)烷基多硫化物和具有一般结构的可固化,低气味(乙烯基芳基)烷基封端的多硫化物共聚物,其中n为约2至约8,1的整数,m为正整数,每个R独立地为 有机多取代基存在于碳原子上,p为零或正整数,其为R和2之间的基团数之间的差异,每个Z独立地选自(乙烯基芳基)烷基和其它非交联单价基团 条件是足够比例的Z基团是(乙烯基芳基)烷基,聚合物固化时不会冷流。 另外,公开了制备所述聚合物的方法和由其制备的有用的粘合剂,密封剂和填缝组合物。
