PURPOSE:To obtain the titled composition outstanding in rigidity, heat, chemical and impact resistances, molding processability, etc., by melting and kneading a polyamide resin having specific chemical structure and rubber-contg. resin. CONSTITUTION:The objective composition can be obtained by melting and kneading (A) 60-90pts.wt. of a polyamide resin made by (co)polymerization of (between), (i) 100-80pts.wt. of a polyamide-forming component from aliphatic diamine (e.g., ethylenediamine), isophthalic acid and terephthalic acid and (ii) 0-20pts.wt. of a lactam (e.g., caprolactam) and/or a second polyamide-forming component from aliphatic diamine and aliphatic dicarboxylic acid (e.g., succinic acid) and (B) 40-10pts.wt. of either (iii) a copolymer made by grafting, to a rubbery polymer, at least two kinds of monomers selected from monovinyl aromatic monomers, unsaturated nitrile monomers and alpha,alpha-monolefinic unsaturated carboxylic acids (derivatives) (e.g. ABS resin) or (iv) a blend of said rubbery polymer and a polymer from two or more kinds of said monomers. |
