The synthesis, characterization and some physical properties of polyvinyl chloride-g-styrene) are described. The graft copolymer was prepared by initiating the polymerization of styrene with polyvinyl chloride) in conjunction with Et2AlCl. Graft copolymer characterization involved GPC, T, heatstability, and intrinsic viscosity studies. Among the physical properties stress-strain and impact strength measurements have been carried out.
