(57) [Summary] [Structure] (A) 0.01 to 1.0 part by weight of (B) aliphatic bisamide relative to 100 parts by weight of poly-ε-caprolactam having a γ-type crystal mixing ratio of 0.4 or more. And (C) 0.01 to 0.8 part by weight of an aliphatic carboxylic acid having 22 or more carbon atoms or its diol ester. [Effect] Since this polyamide resin composition has good melt flowability, extrusion deformation resistance during injection molding, and mold releasability, the molding cycle can be shortened, and the molded product has high rigidity and toughness. There is. |
