POLYAMIDE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a polyamide resin composition which hardly increases blushing when stored in a highly humid atmosphere, when contacted with water or boiling water or when heated to its glass transition temperature or higher and is excellent in mechanical performances such as impact resistance and the like. SOLUTION: This resin composition comprises 100 pts.wt. of a solid phase- polymerized polyamide obtained by solid phase-polymerization of a polyamide obtained by melt polymerization of diamine components containing at least 70 mole % of m-xylylene diamine and dicarboxylic acid components containing at least 70 mole % of adipic acid, and 0.005-1.0 pts.wt. of at least one compound, added thereto, selected from a diamide compound and a diester compound obtained from an 8-30C fatty acid and a 2-10C diamine or diol.
