Abstract: A comolded multi-layered polymer blend system, comprising:at least two layers, each layer having a continuous polymer network of an optionally hydrogenated block copolymer which comprise at least two terminal polymonovinylaromatic blocks and at least one central polyconjugated diene block, and at least one of said layers comprising the continuous polymer network of the block copolymer further comprises a co-continuous rigid polymer phase consisting of a homopolyalkylene or a copolymer of alkylenes having from 2 to 10 carbon atoms;wherein the two layers are in intimate contact with each other;wherein the layers have different contents by weight of the block copolymers; andwherein an extender is present in each polymer network such that the final weight ratio of the block copolymer and the extender in each layer is the same.This comolded multi-layer polymer blend system is used to make air bags for automotive safety systems.

Abstract: A block copolymer containing composition to be used for air bag covers, comprising 100 parts by weight of a selectively hydrogenated block copolymer of a monovinyl aromatic monomer and a conjugated diene, 50-250 parts by weight of a poly(olefin) resin, optionallyt 0-100 parts by weight of a filler having an average particle size of at most 50.mu., and 0.25-2.5 parts by weight of antioxidant/UV stabilizer additives, and air bag covers containing the block copolymer composition.
