PURPOSE:To obtain a composition which does not undergo any change in properties and dimension upon absorption of moisture and is excellent in impact resistance and an appearance of a molding, by mixing a polyamide resin with a specified modified polypropylene and a modified ethylene/alpha-olefin copolymer. CONSTITUTION:A resin composition comprises 95-50wt.% polyamide resin (A), 5-45wt.% modified polypropylene (B) obtained by grafting 0.05-5pts.wt. alpha,beta-unsaturated carboxylic acid and/or its derivative onto 100pts.wt. polypropylene and 1-25wt.% modified ethylene/alpha-olefin copolymer (C) obtained by grafting 0.05-5pts.wt. alpha,beta-unsaturated carboxylic acid and/or its derivative onto 100pts.wt. ethylene/alpha-olefin copolymer, wherein the composition of said component (A), (B) and (C) satisfies the formulas: (A)+(B)+(C)=100wt.% and (B)/(C)>=1. |
