| 摘要 |
The present invention has its object to provide a thermoplastic resin composition which comprises an isobutylene-based block copolymer and a thermoplastic polyurethane resin, and low in hardness and excellent in oil resistance, transparency, thermal stability, mechanical strength and the like. The present invention provides a thermoplastic resin composition which comprises 30 to 95 parts by weight of (a) an isobutylene-based block copolymer constituted of a polymer block the main constituent of which is isobutylene and a polymer block derived from a monomer composition the main constituent of which is not isobutylene and 70 to 5 parts of a thermoplastic polyurethane resin.
