Abstract
The novel thermoplastic elastomer composition of the present invention, which comprises an isobutylene block copolymer (A) containing a polymer block composed predominantly of isobutylene and a polymer block composed predominantly of an aromatic vinyl compound and an alkenyl-terminated isobutylene polymer (B), is highly flexible, and satisfactory in good moldability, rubber-like characteristics, mechanical strengths, permanent compression set characteristics and vibration damping properties.
