The present invention is a composition and a method of forming a composition , the composition comprising at least a halogenated elastomer and an amine or phosphine. An additional rubber component may be present in the composition of the invention. Ine one embodiment, the halogenated elastomer is a isoolefin copolymer comprising a halomethylstyrene derived unit. The amine or phosphin e compound is represented by the formula (R1R2R3)Q, wherein Q is a Group 15 element, and wherein R1 is either hydrogen or a C4 to C30 hydrocarbyl group, R2 is either hydrogen or a C1 to C30 hydrocarbyl group; and R3 is either hydrogren or a C1 to C30 hydrocarbyl group provided that at least one of R1, R2 and R3 is not hydrogen. The additional rubber is selected from butyl rubber, halogenated butyl rubbe, star-branched butyl rubber, halogenated sta r- branched butyl rubber, isobutylene homopolymer, butadiene rubber, neoprene, nitrile rubber, ethylene/propylene/diene terpolymers, ethylene/propylene copolymers, styrene butadiene rubbers, polybutadiene, polyisoprene, isoolefin/alkylstyrene copolymer, halogenated isoolefin/alkylstyrene copolymer, natural rubber, polypropylene, polyethylene, polyurethane, polyvinyl chloride, silicon rubber, propylene oxide polymer, and mixtures thereof. |
