Abstract:
A composition having a compression set (at 100.degree. C. for 22 hours) of 65% or less as rubber, comprising:(a) 100 parts by weight of a hydrogenated block copolymer obtained by hydrogenating a block copolymer comprising at least two polymer blocks composed mainly of a vinyl-substituted aromatic hydrocarbon and at least one polymer block B composed mainly of a conjugated diene,(b) 10 to 150 parts by weight of a polymer selected from the group consisting of a homopolymeric polyphenylene ether resin, a copolymeric polyphenylene ether resin and combinations thereof, comprising a binding unit represented by the general formula, ##STR3##wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4, which may be the same or different, represent substituents selected from the group consisting of hydrogen, halogen, hydrocarbon groups and substituted hydrocarbon groups, and(c) 10 to 500 parts by weight of a substantially amorphous polyolefin or hydrogenated polydiene.
