  • Hydrosilylation crosslinking
    Patent number: 5936028
    Abstract: An improved process for the preparation of thermoplastic elastomers by hydrosilylation crosslinking, in which a platinum containing hydrosilylation catalyst is used in combination with oil which is substantially free of materials which have the chemical behavior of a Lewis base. A crosslinked rubber component is obtained in the thermoplastic elastomer composition.
    Type: Grant
    Filed: November 1, 1996
    Date of Patent: August 10, 1999
    Assignee: Advanced Elastomer Systems, L.P.
    Inventors: Robert Eugene Medsker, Raman Patel, Jianqun Zhao, Gary Gilbertson
  • Phenolic resin curatives which form nonstaining thermoplastic elastomers
    Patent number: 5750625
    Abstract: The phenolic resin curatives used as a curative in thermoplastic elastomers are attributed with staining of painted surfaces which physically contact the thermoplastic elastomers. When the phenolic resin curatives are esterified (e.g., acetylated, tosylated, silylated or phosphorylated) before use as a curative, the amount of staining is reduced or staining is eliminated.

  • Hydrosilylation crosslinking
    Patent number: 5672660
    Abstract: An improved process for the preparation of thermoplastic elastomers by hydrosilylation crosslinking, in which a platinum containing hydrosilylation catalyst is used in combination with specific diene-containing rubbers. A fully crosslinked rubber component is obtained in the thermoplastic elastomer composition.
