THERMOPLASTIC ELASTOMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a new thermoplastic elastomer composition which is rich in flexibility while keeping its damping property as a specific characteristic of an isobutylene-based polymer, is excellent in moldability and a rubberlike characteristic and is especially excellent in a characteristic of compression set. SOLUTION: This thermoplastic elastomer composition comprises a composition prepared by crosslinking an isobutylene-based polymer(A) having an alkenyl group at the terminal by using a compound containing hydrosilyl group in a melt kneading condition in the presence of an aromatic vinyl-based thermoplastic elastomer(B), and an olefin-based polymer(C).
