Abstract
Abstract The invention relates to vinyl-type resin compositions with improved pot life comprising 0.01 to 10 parts by weight of a hardening catalyst and 100 parts by weight of a vinyl-type resin of which the main chain is substantially built up of a vinyl-type polymer which contains at least one silyl radical coupled with a hydrolytic radical at the end groups or in the side chains of each molecule.
