Polyamide resin composition

摘要

A polyamide resin composition comprising: ÄIÜ 100 parts by weight of a polyamide resin (A), and ÄIIÜ 5 to 200 parts by weight of a graft-modified ethylene/ alpha -olefin random copolymer (B) obtainable by graft-modifying an ethylene/ alpha -olefin random copolymer of ethylene and an alpha -olefin of 6 to 20 carbon atoms with an unsaturated carboxylic acid or a derivative thereof and having a graft quantity of 0.01 to 10% by weight based on the weight of the ethylene/ alpha -olefin random copolymer before graft modification, wherein the ethylene/ alpha -olefin random copolymer (B) before the graft modification has the following properties: (a) the content of the alpha -olefin of 6 to 20 carbon atoms is 6 to 25% by mol; and (b) the intrinsic viscosity ( eta ), as measured in decalin at 135 DEG C, is 0.5 to 5.0 dl/g.
