Abstract:
1. A polyamide resin composition comprising a polyamide resin (A), as a matrix, and an ethylene copolymer (C), dispersed therein, having, a functional group (B) reactive with the polyamide resin (A), wherein the tensile stress at break of the ethylene copolymer (C) is 30 to 70% of the tensile stress at break of the polyamide resin (A), and the tensile elongation at break of the modifying polymer (C) is 100 to 500% of the tensile elongation at break of the polyamide resin (A), wherein the ethylene copolymer (C) has a volume fraction of 40 to 80% based on a 100% volume of resin (A) and ethylene copolymer (C) and the functional group is selected from the group consisting of acid anhydride, epoxy, halogen, carboxyl, amino and hydroxyl.
