ABSTRACT:
An internally plasticized polyvinyl halide composition is prepared by polymerizing a vinyl halide in the presence of a reactive polyester plasticizer having terminal groups copolymerizable therewith. The reactive polyester acts as an internal plasticizer for the polyvinyl halide composition and is not readily extactable therefrom.
