Abstract
A polyamide composition comprising 50 to 95 parts by weight of a polyamide and 50 to 5 parts by weight of an ethylenic copolymer of ethylene, an alkyl ester of unsaturated carboxylic acid, an unsaturated carboxylic acid and a metal salt of unsaturated carboxylic acid has excellent processability such as fluidity at melting and remarkably improved impact strength when molded. The polyamide composition may further contain one or more inorganic materials such as glass fiber without lowering physical properties.
