  • Compositions based on mixtures of ethylene-ethyl acrylate copolymers and ethylene-vinyl acetate-vinyl chloride terpolymers
    Patent number: 4648986
    Abstract: Compositions based on mixtures of ethylene-ethyl acrylate copolymers and ethylene-vinyl acetate-vinyl chloride terpolymers which have adhesion to and strippability from crosslinked olefin polymers. Compositions of this invention, which are rendered semi-conductive by the addition of carbon black thereto, are especially useful as outer layers bonded to layers of crosslinked olefin polymer insulation of electrical conductors.
    Type: Grant
    Filed: March 7, 1986
    Date of Patent: March 10, 1987
    Assignee: Union Carbide Corporation
    Inventors: Kunio Kotani, Akio Hayashi, Seiho Taniguchi
