PURPOSE:To obtain a polyamide resin composition, having high ductility and toughness, simultaneously improved in rigidity both at high temperatures and in absorbing moisture and having a high heat distortion temperature with hardly any molding shrinkage. CONSTITUTION:This resin composition consists essentially of 10-89wt.% polyamide resin, 1-30wt.% at least one elastomer selected from elastomers composed of ethylene.propylene.dienes, elastomers composed of ethylene.unsaturated carboxylic acids.unsaturated carboxylic acid esters and elastomers prepared by graft modifying the elastomers and 10-60wt.% amorphous copolymer of ethylene and a cyclic polyolefin having 100-190 deg.C glass transition temperature. |
