摘要：
A modified block copolymer composition comprising a thermoplastic polymer and a modified block copolymer consisting essentially of a base block copolymer of a monovinyl substituted aromatic hydrocarbon polymer block and an olefin compound polymer block having an ethylenic unsaturation degree not exceeding 20%, the base block copolymer having a molecular unit containing a carboxylic acid group and/or a group derived therefrom grafted thereto. The modified block copolymer composition of the present invention is a resinous composition excellent in impact resistance, adhesion, paint adhesion, weatherability, resistance to thermal deterioration, transparency and gloss or a rubbery or leather-like composition excellent in heat resistance, adrasion resistance, compression set resistance, adhesion, transparency, oil resistance, weatherability and resistance to heat aging.
