Abstract: Polyvinyl chloride resin can be plasticized with a carbon monoxide-propylene copolymer. Since the copolymer is soluble in organic solvent, it and the polyvinyl chloride can be dissolved in an organic solvent and then cast to form a film. The copolymer can be a liquid, relatively low molecular weight material, which can be heat blended with the resin along with a smaller amount of a conventional external plasticizer for the resin.

Abstract: An internally plasticized copolymer of from about 50% to about 85%, by weight, vinyl chloride, from about 3% to about 47%, by weight, of a C.sub.6 -C.sub.10 alkyl acrylate, and from about 3% to about 47%, by weight, of a bis(hydrocarbyl)vinylphosphonate is disclosed. This copolymer can be formed by using conventional suspension, emulsion, solution or bulk polymerization procedures and can be utilized without any substantial amount of added external plasticizer in those applications in which externally plasticized vinyl chloride polymers are normally used. The use of such a resin overcomes the plasticizer migration problems associated with externally plasticized polyvinyl chloride systems.
