PURPOSE:To obtain the title composition improved in compatibility and various properties, by mixing a mixture of a vinylaromatic compound/conjugated diene block copolymer with a thermoplastic elastomer with a vinylaromatic compound/ unsaturated carboxylic acid copolymer and/or an isocyanate-modified rubber. CONSTITUTION:100pts.wt. mixture comprising 2-98wt.% block copolymer comprising (desirably, 5-95wt.%, especially, 15-70%) polymer block based on a vinylaromatic compound, especially styrene, and a polymer block based on a conjugated diene, especially 1,3-butadiene, or its hydrogenated product (A), and 2-98wt.% thermoplastic polyurethane elastomer (B) is mixed with 1-100pts. wt. at least either a vinylaromatic compound/unsaturated carboxylic acid copolymer (C-1) or a (co)polymer (C-2) formed by modifying a (co)polymer of a vinylaromatic compound and/or a conjugated diene compound with an isocyanate to obtain a thermoplastic polymer composition. |
