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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
150 words
A polymer-in-monomer solution suitable for use as an adhesive when combined with polymerization catalyst, which when so combined gives bonds that can be characterized by at least one of the following: the setting time is less than about 10 minutes, the T-peel strength is greater than about 5 pli, the lap shear strength on prepared surfaces is greater than about 2500 psi, and the bond strength on oily surfaces is not significantly adversely affected by the presence of the oil, said solution consisting essentially of (a) chlorosulfonated polyethylene made from branched polyethylene having a melt index of about 100, said chlorosulfonated polyethylene containing about 43% by weight chlorine and about 34 mmoles of sulfonyl chloride per 100 grams of polymer and (b) a mixture of the following acrylic monomers: methyl methacrylate, glacial methacrylic acid and ethylene glycol dimethacrylate, said solution having a Brookfield viscosity of up to about 1 million.
Claim 2
Dependent Claim
