Abstract
PURPOSE: To produce a novel thermoplastic copolymer excellent in moldability, mechanical strength, dimensional accuracy, abrasion resistance, etc., by reacting a polyamide with an unsaturated carboxylate ester copolymer of a specified composition under conditions of melt mixing.
CONSTITUTION: There is produced an unsaturated carboxylate ester copolymer having a composition: α,β-unsaturated carboxylate ester: 50W99mol%, imide compound of an α,β-unsaturated dicarboxylic acid; 1W30mol% and monomer copolymerizable therewith: 0W49mol%. By reacting the copolymer with a polyamide under conditions of melt mixing, it is possible to produce a novel copolymer in which the copolymer chain portion is bonded to the polyamide chain portion. This copolymer is thermoplastic and excellent in moldability, mechanical strength, dimensional accuracy, abrasion resistance, chemical resistance and heat resistance.
