Patents by Inventor Jan Bussink

Jan Bussink has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Composition of a selectively hydrogenated block copolymer of a vinyl aromatic compound and a diolefin, a polycarbonate and an amorphous polyester
    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).
    Type: Grant
    Filed: November 9, 1979
    Date of Patent: May 12, 1981
    Assignee: General Electric Company
    Inventors: Jan Bussink, Jean M. H. Heuschen
  • Composition of a polyphenylene ether, a styrene resin, a precompounded polymer system and a block copolymer of a vinyl aromatic compound and an olefinic elastomer
    Patent number: 4145377
    Abstract: There are provided compositions comprising (a) a polyphenylene ether; (b) a polystyrene resin; (c) a precompounded polymer system comprising an olefinic resin and an elastomeric block copolymer alone, or in further combination with a dispersing agent; and (d) an elastomeric block copolymer resin. The use of (c) and (d) together provides, surprisingly, higher impact strength over the entire composition range of (a) to (b), with lower amounts of (c) and (d), based on the total resinous components of the system, being required.
    Type: Grant
    Filed: December 3, 1976
    Date of Patent: March 20, 1979
    Assignee: General Electric Company
    Inventors: Jan Bussink, Johannes W. J. DE Munck
  • Polyblend composition comprising aromatic polycarbonate, polyolefin, selectively hydrogenated block copolymer and olefinic copolymer
    Patent number: 4122131
    Abstract: There are provided compositions comprising (a) an aromatic polycarbonate resin; and (b) a precompounded polymer system comprising an olefinic resin and a selectively hydrogenated elastomeric block copolymer resin, alone or in further combination with an aromatic polycarbonate or styrene resin and, optionally a hydrogenated elastomeric block copolymer resin. The use of (a) and (b) together provides high impact strength and unexpectedly superior flowability in the molten state.
