  • Polyorganosiloxane/polyvinyl-based graft (meth)acrylate polymers
    Patent number: 5106908
    Abstract: A multi-stage polyorganosiloxane/polyvinyl-based graft polymer is provided by the co-homopolymerization of organosiloxanes and a vinyl-based monomer (e.g. styrene) and the subsequent graft polymerization of one or more stages of additional (meth)acrylate monomers, vinyl aromatic/(meth)acrylate comonomers or vinyl aromatic/vinyl cyanide/(meth)acrylate termonomers with or without an intermediary stage comprising a polymer.
    Type: Grant
    Filed: November 14, 1988
    Date of Patent: April 21, 1992
    Assignee: General Electric Company
    Inventors: Muhanad A. Alsmarraie, Stanley Y. Hobbs, I-chung W. Wang, Vicki H. Watkins
  • Polyester, polycarbonate and/or polyphenylene ether with polyorganosiloxane/polyvinyl-based graft (meth) acrylate polymers
    Patent number: 5087662
    Abstract: Thermoplastic molding compositions are provided which comprise polycarbonate resins, polyester resins and polyphenylene ether resins or various combinations thereof modified with a multi-stage polyorganosiloxane/polyvinyl-based graft (meth)acrylate polymer. When the resultant compositions are molded, impact strength, ductility, tendency to agglomerate, rubber dispersion, blend morphology, weld line strength, and thermal stability are improved with no delamination or surface mottling.
