  • Process for producing an iminated copolymer
    Patent number: 4591619
    Abstract: A thermoplastic resin composition is provided which comprises 10 to 90 wt % of an iminated copolymer prepared by reacting ammonia and/or a primary amine with a graft copolymerization product obtained by graft-copolymerizing a rubber-like polymer with a monomer mixture containing an aromatic vinyl monomer and an unsaturated dicarboxylic acid anhydride and 10 to 90 wt % of a graft-copolymer obtained by graft-copolymerizing a rubber-like polymer with a monomer mixture containing an aromatic vinyl monomer and/or a polymer obtained by polymerizing an aromatic vinyl monomer.
    Type: Grant
    Filed: December 21, 1984
    Date of Patent: May 27, 1986

  • Catalysts for polymerization of olefins
    Patent number: 4425258
    Abstract: A solid catalyst for olefin polymerization is obtained by treating magnesium halide with a sulfur compound or sulfur and a sulfur compound and further treating with an electron donor compound and a halogen-containing titanium compound. Alternatively, the magnesium halide is treated with halogen and/or an interhalogen compound and sulfur and/or a sulfur compound and is further treated with an electron donor compound and a halogen-containing titanium compound. The solid catalyst thus obtained is used for a catalytic system for olefin polymerization in combination with an organometallic compound.

  • Heat resistant resin composition
    Patent number: 4404322
    Abstract: A heat resistant thermoplastic resin composition is provided which comprises an iminated copolymer prepared by iminating a copolymer obtained by copolymerizing an aromatic vinyl monomer, maleic acid anhydride and a vinyl monomer copolymerizable with the aromatic vinyl monomer and maleic acid anhydride with the use of ammonia and/or a primary amine, and mixed with a graft polymer with or without a styrene base polymer.
    Type: Grant
    Filed: January 20, 1982
    Date of Patent: September 13, 1983
    Assignee: Denki Kagaku Kogyo Kabushiki Kaisha
    Inventors: Kiyotaka Saito, Tomoyuki Kitsunai, Shozo Hori
  • Catalysts for polymerization of olefins
    Patent number: 4325838
    Abstract: A solid catalyst for olefin polymerization is obtained by treating magnesium halide with halogen or a halogen compound and further treating with an electron donative compound and a halogen-containing titanium compound. The halogen atom of the halogen or halogen compound as the treating agent must be different from the halogen atom of magnesium halide as the substrate.This solid catalyst is used for a catalytic system for olefin polymerization in combination with an organometallic compound.
