Abstract
The high nitrile graft copolymer is provided and a high nitrile resin composition impact modified thereby is also provided. Brittle high nitrile resins can be effectively impact modified by the addition of a high nitrile graft copolymer thereto. The high nitrile graft copolymer contains a rubber substrate and a polymeric graft portion superstrate. The substrate contains high levels of diene and amounts of vinyl cyanide and alkylmethacrylate. The polymeric graft portion (superstate) contains high level of vinyl cyanide and a vinyl aromatic hydrocarbon. The high nitrile resin composition is useful as a resin for making chemical resistant high impact molded articles.
