摘要：
An improved process for the preparation of thermoplastic vulcanizates from butyl rubbers by hydrosilylation crosslinking of acrylic or alkacrylic functionalized copolymers of isobutylene and paramethylstyrene is disclosed. The functionalization results in lower compression and tension set than when using conventional butyl rubbers. Other physical properties of the thermoplastic vulcanizate are improved consistent with more efficient crosslinking of the functionalized copolymer.
