MODIFIZIERTES BLOCK-COPOLYMER.

摘要

A modified block copolymer composition comprising a polyamide and a modified block copolymer consisting essentially of a base 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%, said base block copolymer having a molecular unit containing a carboxylic acid group andtor a group derived therefrom grafted thereonto. The modified block copolymer composition of the present invention is a resinous composition excellent in impact resistance, adhesion, paint adhesion, a weatherability, resistance to thermal deterioration, transparency and gloss or a rubbery or leather-like composition excellent in heat resistance, abrasion resistance, compression set resistance, adhesion, transparency, oil resistance, weatherability and resistance to heat aging.
