  • Chlorinated EPDM with superior stability
    Patent number: 5045603
    Abstract: A chlorinated ethylene-alpha olefin-nonconjugated diolefin terpolymer having a chlorine content of from about 0.5 to 14 percent by weight characterized by superior viscosity stability on storage or exposure to elevated temperatures is obtained by chlorinating an ethylene-alpha olefin-nonconjugated diolefin terpolymer wherein said nonconjugated diolefin is an acyclic nonconjugated diolefin characterized in that one olefinic bond is monosubstituted and terminal and the other olefinic bond is trisubstituted. A vulcanizable rubber composition comprising said chlorinated ethylene-alpha olefin-nonconjugated diolefin terpolymer and cure active agents is also provided.
    Type: Grant
    Filed: July 19, 1990
    Date of Patent: September 3, 1991
