ABSTRACT:
Polyblends of a vinyl chloride polymer having good low temperature crack propagation resistance, overall toughness and high resiliency comprising a polyvinyl chloride polymer and a two stage core grafted composite copolymer having a particular butadiene-styrene rubbery substrate. The composite graft copolymer is blended with a matrix of a polyvinyl halide resin and modified with a plasticizer, stabilizer and lubricant system to provide the desired tough rubbery polyblends for molding.
