  • Organopolysiloxanes modified with poly-carbodiimide
    Patent number: 4214066
    Abstract: Polycarbodiimide is present as a solid phase in a liquid polyorganosiloxane, preferably being formed therein by mixing a polyisocyanate with the polysiloxane followed by a carbodiimidization catalyst. If the polyorganosiloxane contains hydroxyl groups it can be chemically bonded to the polycarbodiimide. The composition can be cured to solid plastic masses of superior properties by adding a curing agent for the polysiloxane.
    Type: Grant
    Filed: June 22, 1978
    Date of Patent: July 22, 1980
    Assignee: Bayer Aktiengesellschaft
    Inventors: Hans-Heinrich Moretto, Helmut Steinberger, Ingrid Larking, Hans Sattlegger
  • Organopolysiloxane compositions modified with polyurethane
    Patent number: 4202807
