摘要：
Polyamide resin compositions which are useful for molding parts with excellent malleability, toughness, rigidity, and high heat deformation temperatures are prepared from 10 to 89 % by weight of a polyamide resin, 1 to 30 % by weight of at least one type of elastomer selected from among elastomers composed of ethylene/propylene/dienes, elastomers composed of ethylene/unsaturated carboxylic acid unsaturated carboxylic acid esters, and elastomers obtained by graft-modifying these elastomers, and from 10 to 60 % by weight of a copolymer of ethylene and cyclic olefin that is noncrystalline and has a glass transition temperature of from 100 to 190 DEG C.
