Thermoplastic polymeric material and method for the preparation thereof

摘要

A thermoplastic polymeric material which is superior in mechanical strength comprises (1) 10 to 65% by weight of a hard copolymer containing as a comonomer an alpha , beta -unsaturated dicarboxylic acid anhydride and (2) 90 to 35% by weight of a polyamide, which are chemically bonded to each other. The thermoplastic polymeric material has a fine dispersion microstructure. The material may be reinforced by incorporating glass or carbon fibers therein.
