THERMOPLASTIC RESIN COMPOSITION

摘要

Provided is a resin composition which is excellent in gas barrier property, mechanical strength and elasticity, and further is reduced in the deformation owing to the weight of itself and in the staining property even under a high temperature condition. A thermoplastic resin composition characterized in that it comprises an isobutylene based polymer (A) which has a number average molecular weight and a weight average molecular weight being 20,000 to 200,000 respectively, and contains a component having a molecular weight of less than 10,000 in an amount of 5 wt % or less.
