An object of the present invention is to provide anthermoplastic elastomer composition which is highly flexible whilenmaintaining vibration damping properties, as a feature of annisobutylene polymer, and is excellent in moldability andnrubber-like properties, and also has particularly improvednpermanent compression set. The object is achieved by anthermoplastic elastomer composition comprising (A) a compositionnobtained by crosslinking an isobutylene polymer having an alkenylngroup at the molecular ends with a hydrosilyl group-containingncompound while melt-kneading in the presence of at least one kindnselected from an aromatic vinyl-containing thermoplasticnelastomer and an olefinic resin, and (B) at least one kind selectednfrom the group consisting of an aromatic vinyl-containingnthermoplastic elastomer and an olefinic resin. |
