<P>PROBLEM TO BE SOLVED: To provide a polyamide resin composition and a molded article having excellent stability of surface appearance and impact resistance and causing little lowering of mold releasability by change of molding conditions. <P>SOLUTION: The polyamide resin composition includes (A) a polyamide including (a) a unit composed of adipic acid and hexamethylenediamine and (b) a unit composed of isophthalic acid and hexamethylenediamine and satisfying the formulas 0.05≤(x)≤0.5 and -0.3≤(Y)≤0.8, wherein (x) is the ratio of isophthalic acid component in the total carboxylic acid component, (Y) is defined by formula (1): (Y)=[(EG)-(x)]/[1-(x)], and (EG) is the ratio of isophthalic acid terminal group in the total carboxyl terminal groups in the polyamide (A) and expressed by formula (2): (EG)=(amount of isophthalic acid terminal group)/(total carboxyl terminal group)...(2); and (B) at least one kind of moldability improving agent selected from higher fatty acids, higher fatty acid metal salts, higher fatty acid esters and higher fatty acid amides. <P>COPYRIGHT: (C)2013,JPO&INPIT |
