  • High clarity blends of polycarbonates with mercaptan-modified graft polymers
    Patent number: 4145374
    Abstract: Blends of polycarbonates with from 3 to about 10 weight per cent of a graft polymer having incorporated therein pendent phenalkyl groups exhibit markedly decreased notch sensitivity. The blends have remarkably high clarity and low haze.
    Type: Grant
    Filed: October 27, 1977

    Assignee: Borg-Warner Corporation
    Inventors: Kenneth W. Narducy, John C. Falk, Murray S. Cohen
  • High impact polyblends from hydrogenated butadiene polymers
    Patent number: 3985829
    Abstract: High impact thermoplastic polyblend compositions prepared by polymerizing vinylaromatic and/or vinyl nitrile monomers in the presence of rubbery substrates of fully hydrogenated 1,2-polymerized butadiene and copolymers thereof. The products exhibit surprisingly high impact and tensile properties despite a very low content of graft polymer.
