Abstract
A method of making a composition useful for making a copolymer laminate with polyvinyl chloride. The copolymer is an alkyl acrylate or alkyl methacrylate where the alkyl group contains 1 to 30 carbon atoms and vinyl nitrile. Improved adhesion is achieved when 1 to 50 parts of organic isocyanate or polyisocyanate is used per 100 parts of polyvinyl chloride (or 100 parts of copolymer) where the polyvinyl chloride contains high amounts of plasticizer.
