Abstract
Abstract Solutions of chlorosulfonated polyethylene or mixtures of sulfonyl chlorides and chlorinated polymers in polymerizable vinyl monomers having a Brookfield viscosity of up to about 1 million form excellent adhesive compositions which cure to high bond strengths. Acrylic monomers are preferred.
