The present invention is a blend and a method of making the blend, wherein the blend comprises at least one halogenated elastomer and an amine or phosphine. The added rubber component may be present in the formulation of the present invention. In some embodiments, the halogenated elastomer is an isoolefin copolymer containing units derived from homomethylstyrene. The amine or phosphine compound is represented by the formula (R 1 R 2 R 3 ) Q, wherein Q is a Group 15 element, wherein R 1 is hydrogen or a C 4 -C 30 hydrocarbyl group, R 2 is hydrogen or The C 1 -C 30 hydrocarbyl group, and R 3 are hydrogen or a C 1 -C 30 hydrocarbyl group, wherein at least one of R 1 , R 2 and R 3 is not hydrogen. The rubber to be added is butyl rubber, halogenated butyl rubber, star butyl rubber, halogenated star butyl rubber, isobutylene homopolymer, butadiene rubber, neoprene, nitrile rubber, ethylene / propylene / diene terpolymer, ethylene / propylene copolymer, styrene butadiene rubber, It is selected from polybutadiene, polyisoprene, isoolefin / alkylstyrene copolymer, halogenated isoolefin / alkylstyrene copolymer, natural rubber, polypropylene, polyethylene, polyurethane, polyvinyl chloride, silicone rubber, propylene oxide polymer, and mixtures thereof. |
