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.
