ABSTRACT:
Liquid vinylidene (CH.sub.2 .dbd.C<) terminated polymers are prepared by the reaction of a (1) liquid polymer having a terminal functional group selected from the group consisting of carboxyl, hydroxyl, mercaptan, amine and epoxy and (2) a compound containing both an epoxy group ##STR1## and a vinylidene group. The reaction can be catalyzed using a base. The polymers cure readily to solid elastomers which are useful as sealants, caulks, potting compounds, coatings and the like.
