<p>Improved liquid vinylidene terminated polymers having long term shelf stability are prepared by the reaction of a (1) liquid polymer having a terminal functional group such as carboxyl, hydroxyl and mercaptan, with (2) a compound containing both an epoxy group and a vinylidene group in the presence of carboxylic acid. The polymers cure readily to solid elastomers which are useful as sealants, caulks, potting compounds, coatings and the like.</p> |
