Abstract
Abstract A resin composition for molding materials, said composition comprising (I) 100 parts by weight of a resin composition composed of (A) 5 to 95 parts by weight of a polyamide resin composed of 1 to 99% by weight of a polyamide resin obtained from xylylenediamine and an alpha, omega-linear aliphatic dibasic acid and 99 to 1% by weight of nylon 66, and (B) 95 to 5 parts by weight of a styrene-acrylonitrile copolymer containing 5 to 50 mole % of acrylonitrile as a copolymer component, and (II) 5 to 150 parts by weight of an inorganic filler.
