ABSTRACT:
Organosilicon compounds having alkynol groups and containing units of the formulawhere R3and R2are optionally substituted hydrocarbon radicals, R4are divalent organic radicals, and X is a linking group are useful in addition crosslinkable compositions. The compositions exhibit long pot life and yet also exhibit excellent cure, and are useful, inter alia, in preparing molded articles and coatings.
