ABSTRACT:
Vinyl halide polymers, preferably polyvinyl chloride, which exhibit improved processing characteristics without sacrificing physical properties are prepared by partially polymerizing vinyl halide monomer at a first reaction temperature and then changing the reaction temperature and continuing the polymerization at a second temperature conducive to forming a polymer of an average molecular weight range different from that obtainable at the first reaction temperature. The product provides the physical characteristics of polymer blends but can be processed without formation of fish eyes.
