摘要： A thermoplastic vulcanizate prepared by dynamically vulcanizing a halogenated butyl rubber within a mixture that includes the halogenated butyl rubber and from about 10 to about 100 parts by weight of a crystalline thermoplastic resin per 100 parts by weight rubber, to thereby form a thermoplastic vulcanizate, where the thermoplastic resin includes a resin other than polyethylene, melt mixing the thermoplastic vulcanizate with about 5 to about 75 parts by weight of polyethylene resin per 100 parts by weight rubber, from about 3 to about 60 parts by weight of a tackifier per 100 parts by weight rubber, and from about 5 to about 250 parts by weight of a block copolymer containing at least the structure S-B/S-S per 100 parts by weight rubber, where the S block of the block copolymer has a glass transition temperature above about 25° C., the B/S block has a glass transition temperature below about 25° C., and the S content of the B/S block is from about 40 to about 60 percent by weight of said S/B block, the diene content of the total block copolymer is less than 40 weight percent, and the B/S block amount to at least 50 weight percent of the total block copolymer.
