  • Polyvinyl chloride polyblend molding composition
    Patent number: 3985693
    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.
    Type: Grant
    Filed: June 27, 1974
    Date of Patent: October 12, 1976
    Assignee: Monsanto Company
