PURPOSE:To provide the titled composition having excellent moldability, abrasion resistance and dyeability, by compounding an ethylenic unsaturated nitrile- diene rubber-aromatic vinyl copolymer with a thermoplastic polyurethane elastomer and a thermoplastic polyester resin, etc. CONSTITUTION:The objective composition can be produced by mixing (A) 90-55 pts.(wt.) of an ethylenic unsaturated nitrile-diene rubber-aromatic vinyl copolymer, preferably an ABS resin with (B) 5-40pts., preferably 10-35pts. of an thermoplastic polyurethane elastomer (either of the ester-type one such as adipic acid polyester, carprolactone polyester etc. of the polyether-type one can be used) and (C) 5-30pts., preferably 10-25pts. of one or more resins selected from a thermoplastic polyester resin (e.g. PET, PBT, etc.), a polyacetal resin (e.g. polyoxymethylene homopolymer) and a polyamide resin (nylon). The mixing is carried out by dry-blending or melt-mixing.
