PROCESS FOR PRODUCING VINYL POLYMER HAVING ALKENYL GROUP AT END, VINYL POLYMER, AND CURABLE COMPOSITION

摘要

A process for easily producing an alkenyl-terminated vinyl polymer without using a metal compound necessitating a complicated purification step; and a curable composition containing the vinyl polymer. An alkenyl group is incorporated into an end of a vinyl polymer having a thiocarbonylthio structure at the end to produce an alkenyl-terminated vinyl polymer. Mixing this vinyl polymer with a compound having a hydrogen-silicon bond and a hydrosilylation catalyst gives the curable composition.
