PROBLEM TO BE SOLVED: To obtain a polyphenylene sulfide(PPS) resin composition having excellent toughness, moldability, low gas emission and high weld strength as well as excellent heat-resistance and mechanical properties. SOLUTION: The objective PPS resin composition contains (A) 100 pts.wt. of a PPS resin and (B) 1.5-35 pts.wt. of an epoxy-containing olefin copolymer produced by the copolymerization of anα-olefin, anα,β-unsaturated carboxylic acid alkyl ester and an epoxy-containing vinyl monomer as essential copolymerization units. The copolymerization ratio of theα-olefin is 52-95 wt.% and that of theα,β-unsaturated carboxylic acid alkyl ester is 5-48 wt.%. The amount of the epoxy-containing vinyl monomer is 0.5-15 wt.% based on 85-99.5 wt.% of the sum of theα-olefin and theα,β-unsaturated carboxylic acid alkyl ester.
