    • A thermoplastic polymer composition consisting essentially of:(a) at least one member selected from the group consisting of a block copolymer consisting of a polymer block comprising at least 60% by weight of an alkenyl aromatic compound and a polymer block comprising at least 60% by weight of a conjugated diene compound and a hydrogenated product of said copolymer;(b) a thermoplastic polyurethane elastomer and(c) at least one member selected from the group consisting of the following (c-1) and (c-2) components:(c-1): a copolymer of an alkenyl aromatic compound with at least one compound selected from the group consisting of an unsaturated carboxylic acid and its derivative,(c-2): a modified (co)polymer obtained by reacting an isocyanate with a (co)polymer of at least one compound selected from the group consisting of an alkenyl aromatic compound and a conjugated diene compound; or a hydrogenated product of the modified (co)polymer or a mixture of the isocyanate-modified (co)polymer with the hydrogenated product,wherein the (a)/(b) weight ratio is 2/98-98/2 and the proportion of the (c) component is 1-100 parts by weight per 100 parts by weight of a total of the (a) and (b) components. The above composition is excellent in compatibility between the (a) component and the (b) component, and hence, has excellent heat resistance, mechanical strengths and wear resistance.
