THERMOPLASTIC RESIN COMPOSITION

摘要

PURPOSE:To obtain a thermoplastic resin compsn. having excellent compatibility and mechanical properties, by blending a modified polyolefin obtd. by grafting an unsaturated carboxylic acid and a silane compd. with a polyamide. CONSTITUTION:A resin compsn. consists of 5-95wt% modified polyolefin (A) obtd. by grafting an unsaturated carboxylic acid or its derivative and a silane compd. or modified polyolefin (A) obtd. by diluting said modified polyolefin with a polyolefin and 95-5wt% polyamide (B). A polymer mainly composed of propylene such as polypropylene or a random or block copolymer obtd. by copolymerizing propylene with ethylene or other alpha-olefin is preferred as the polyolefin. The amount of the unsaturated carboxylic acid or derivative to be grafted is pref. 0.001-10wt%.
