Abstract
A method of making a composition useful for making a terpolymer laminate with polyvinyl chloride, polyurethanes and metals. The terpolymer is an alkyl acrylate or alkyl methacrylate where the alkyl group contains 1 to 30 carbon atoms with vinyl nitrile and N,N'-dimethylacrylamide. Improved adhesion is achieved where 1 to 50 parts of organic isocyanate or polyisocyanate is used per 100 parts of terpolymer, where the PVC contains high amounts of plasticizer and with some polyurethanes and metals.
