A thermoplastic resin composition comprising a rubber-reinforced thermoplastic resin as component (A) and an ethylene-α-olefin copolymer having a Mooney viscosity (ML1+4, 100° C.) of 40 to 110 as component (B), the amount of component (B) being 1 to 70 parts by weight based on 100 parts by weight of component (A).
A thermoplastic resin composition comprising a rubber-reinforced thermoplastic resin as component (A) and an ethylene-α-olefin copolymer having a Mooney viscosity (ML1+4, 100° C.) of 40 to 110 as component (B), the amount of component (B) being 1 to 70 parts by weight based on 100 parts by weight of component (A),
- said component (A) comprising:
- 100 parts by weight of a rubber-reinforced thermoplastic resin (A1) obtained by polymerizing 5 to 94% by weight of an aromatic vinyl compound, 1 to 90% by weight of a vinyl cyanide compound and 0 to 89% by weight of other copolymerizable compound (the total of the ratios of the respective components being 100% by weight) in the presence of 5 to 80% by weight of a rubber-like polymer (i) which is an ethylene-α-olefin-(nonconjugated diene) copolymer, and
- 1 to 70 parts by weight of a rubber-reinforced thermoplastic resin (A2) obtained by polymerizing 5 to 94% by weight of an aromatic vinyl compound, 1 to 90% by weight of a vinyl cyanide compound and 0 to 89% by weight of other copolymerizable compound (the total of the ratios of the respective components being 100% by weight) in the presence of 5 to 80% by weight of a rubber-like polymer (ii),
- which rubber-like polymer (ii) is a hydrogenated block copolymer obtained by hydrogenating a block copolymer comprising an aromatic vinyl compound unit and a conjugated diene compound unit, the number-average molecular weight (Mn) of the block copolymer being 5,000 to 1,000,000, the ratio of weight-average molecular weight (Mw) to number-average molecular weight (Mn), Mw/Mn, being not more than 10, the vinyl bond content of the diene moiety being 10 to 90%, and the hydrogenation rate of the olefinic unsaturated bond is not less than 70%.
