    • An object of the present invention is to provide a thermoplastic elastomer composition which is highly flexible while maintaining vibration damping properties, as a feature of an isobutylene polymer, and is excellent in moldability and rubber-like properties, and also has particularly improved permanent compression set. The object is achieved by a thermoplastic elastomer composition comprising (A) a composition obtained by crosslinking an isobutylene polymer having an alkenyl group at the molecular ends with a hydrosilyl group-containing compound while melt-kneading in the presence of at least one kind selected from an aromatic vinyl-containing thermoplastic elastomer and an olefinic resin, and (B) at least one kind selected from the group consisting of an aromatic vinyl-containing thermoplastic elastomer and an olefinic resin.
    • 本发明的目的是提供一种热塑性弹性体组合物,其特征在于,作为异丁烯类聚合物的特征而具有高弹性,同时保持振动阻尼性能,并且成型性和橡胶状特性优异,并且还具有特别改进的永久压缩永久变形 。 该目的通过一种热塑性弹性体组合物来实现,该组合物包含(A)通过将分子末端具有烯基的异丁烯聚合物与含氢化甲硅烷基化合物交联而获得的组合物,同时在选自以下的至少一种的存在下熔融捏合 含芳族乙烯基的热塑性弹性体和烯烃树脂,和(B)选自含芳族乙烯基的热塑性弹性体和烯烃树脂中的至少一种。
