ABSTRACT:
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.
