ABSTRACT:
A new rubber composition, the vulcanizate of which has reduced permeability to gases, comprises: one hundred parts by weight of at least one butyl-type rubbery polymer; from about 3 to about 20 parts by weight of .alpha.-methylstyrene homopolymer having a softening point of from about 93.degree. C. to about 150.degree. C. and a Tg of from about 15.degree. C. to about 75.degree. C.; from about 30 to about 90 parts by weight of at least one carbon black, from 0 to about 7 parts by weight of hydrocarbon extender oil; and a curing system. A process for producing said rubber composition is also provided.
