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.
