  • Patent number: 4539350
    Abstract: High impact, high modulus thermoplastic molding compositions comprising:(a) a linear polyester;(b) a fibrous reinforcing agent essentially free of any sizing agent; and(c) a small amount of a polysiloxane having a substantial content of Si-H bonds.
    Type: Grant
    Filed: July 9, 1981
    Date of Patent: September 3, 1985
    Assignee: General Electric Company
    Inventors: Petrus C. A. M. V. Abeelen, Jan Bussink, Jean M. H. Heuschen
  • Patent number: 4504623
    Abstract: A method of preparing a polymer mixture comprising polyvinyl chloride, an aromatic polycarbonate and a rubber like polymeric, characterized in that first a premixture comprising 60-90% by weight of aromatic polycarbonate and 10-40% by weight of rubber like polymer is prepared by mixing at a temperature above about 220.degree. C., after which the resulting premixture is cooled to a temperature below about 220.degree. C. and is mixed with the polyvinyl chloride.
    Type: Grant
    Filed: December 9, 1983
    Date of Patent: March 12, 1985
    Assignee: General Electric Company
    Inventors: Jean M. H. Heuschen, Jan Bussink, Willem L. Sederel
  • Patent number: 4504624
    Abstract: A polymer mixture comprising polyvinyl chloride, an aromatic polycarbonate and a rubber like polymer, characterized in that the rubber like polymer is a graft copolymer which is built up from a rubber like main chain with predominantly alkyl acrylate units on which styrene, .alpha.-methylstyrene, acrylonitrile, methacrylic acid esters, acrylic acid esters or mixtures thereof have been grafted.
    Type: Grant
    Filed: December 9, 1983
    Date of Patent: March 12, 1985
    Assignee: General Electric Company
    Inventors: Jean M. H. Heuschen, Jan Bussink, Willem L. Sederel
  • Patent number: 4267096
    Abstract: There are provided compositions comprising (a) a selectively hydrogenated elastomeric block copolymer, (b) a polycarbonate and (c) an amorphous polyester. The use of the combination of (a) and (c) provides remarkable improvements in the melt flow characteristics, in resistance to brittle failure, and in the resistance to environmental stress crazing and cracking of the polycarbonate resin component (b).
