ABSTRACT OF THE DISCLOSURE 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 C6-C10 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 convention- al suspension, emulsion, solution or hulk polymerization pro- cedures and can by utilized without any substantial amount of added external plasticizer in those applications in which ex- ternally plasticized vinyl chloride polymers are normally used. The use of such a resin overcomes the plasticizer migration prob- lems associated with externally plasticized polyvinyl chloride systems. * * * * *
