摘要：
A thermoplaslic polymer composition comprising:
(i) 100 parts by weight of a thermoplastic polymer component which comprises an ethylene-propylene rubber, an ethylene copolymer and a propylene polymer (including an ethylene-propylene block copolymer), and (ii) 7 to 25 parts by weight of talc, the thermoplastic polymer component being composed of, according to fractionation using o-dichlorobenzene as a solvent, component (A) which is a component soluble in the solvent at 40°C, component (B) which is a component insoluble in the solvent at 40°C but soluble at 110°C, and component (C) which is a component insoluble in the solvent even at 110°C in such a proportion that the total amount of the components (A) and (B) is from 50 to 70 parts by weight, the weight ratio of the component (A) to the component (B) being from 0.5 to 1.5, and the amount of the component (C) is from 50 to 30 parts by weight; said composition having a flexural modulus of 10,000 to 20,000 kg/cm².
