ABSTRACT:
An internally plasticized polyvinyl halide obtained by the polymerization of a vinyl halide monomer in the presence of a polyester polymeric plasticizer substantially derived from glutaric acid and a diol Articles made therefrom exhibit a unique balance of improved permanence, low plasticizer extraction high clarity and low haze. The polymers are particularly suitable for use in automotive interior parts or containers for blood components or foodstuffs.
