  • Graft copolymers containing rubber, acrylonitrile and an aromatic olefin
    Patent number: 4205020
    Abstract: A graft copolymer comprises a substrate of a diene rubber, and a homogeneous superstrate containing units of acrylonitrile and at least one aromatic olefin having a molar ratio of acrylonitrile to olefin between 2 and 9. The superstrate may also contain a minor amount (preferably less than 10 mole %) of at least one other comonomer selected from acenaphthylene, vinyl carbazole and its derivatives, maleimide and its N-substituted derivatives and norbornene and its derivatives.
    Type: Grant
    Filed: February 13, 1979
    Date of Patent: May 27, 1980
    Assignee: Imperial Chemical Industries Limited
    Inventors: Brian N. Hendy, Carl F. Mathews, Eric Nield, John B. Rose, Peter I. Vincent
  • Transition metal catalyst
    Patent number: 4193893
    Abstract: A transition metal product, for example a titanium trichloride material, is obtained by milling a solid transition metal compound with a carboxylic acid or an ester thereof, for example methylmethacrylate and contacting with an organo-Lewis Base such as an amine, an organo-phosphorus compound or a sulphone derivative. The organo-Lewis Base may be milled with the transition metal compound or may be added to the transition metal compound as a solution in an inert liquid. The product can be used as a component of an olefine polymerization catalyst.
    Type: Grant
