  • Process for vulcanizing saturated elastomers with halogen cure sites
    Patent number: 4876315
    Abstract: A composition of matter is disclosed comprising a saturated elastomer having an active halogen-containing cure site, sulfur and a quaternary ammonium salt of a mineral acid. The invention also provides a process for vulcanizing the above composition.
    Type: Grant
    Filed: June 6, 1988
    Date of Patent: October 24, 1989
    Assignee: National Distillers and Chemical Corporation
    Inventors: John M. Hoyt, Steven D. Blazey

    Patent number: 4808669
    Abstract: A composition of matter is disclosed comprising a saturated elastomer having an active halogen-containing cure site, sulfur and a quaternary ammonium salt of a mineral acid. The invention also provides a process for vulcanizing the above composition.
    Type: Grant
    Filed: June 6, 1988
    Date of Patent: February 28, 1989
    Assignee: National Distillers and Chemical Corporation
    Inventors: John M. Hoyt, Steven D. Blazey
  • Phase transfer compounds as accelerators of soap/sulfur vulcanization
    Patent number: 4806584
    Abstract: A composition of matter is disclosed comprising (1) a saturated elastomer having an active halogen-containing cure site, (2) a soap/sulfur cure system, and (3) a phase transfer compound. The phase transfer catalyst comprises a quaternary ammonium or phosphonium salt of a mineral acid or an alkylene oxide polymer. The phase transfer compounds accelerate soap/sulfur cures and make it possible to obtain acceptable cure rates with higher fatty acid soaps.
