Abstract
A polyphenylene sulfide resin composition having excellent impact properties is provided which comprises: (A) a polyphenylene sulfide resin and (B) an olefinic copolymer containing 60 to 99.5% by weight of an .alpha.-olefin and 0.5 to 40% by weight of a glycidyl ester of an .alpha.,.beta.-unsaturated carboxylic acid, and which is characterized in that the polyphenylene sulfide resin (A) is contacted to improve its affinity with the olefinic copolymer (B).

A polyphenylene sulfide resin composition comprising:
- (A) 99.5 to 50% by weight of a polyphenylene sulfide resin and
- (B) 0.5 to 50% by weight of an olefinic copolymer containing 60 to 99.5% by weight of an .alpha.-olefin and 0.5 to 40% by weight of a glycidyl ester of an .alpha.,.beta.-unsaturated carboxylic acid, characterized in that said polyphenylene sulfide resin (A) is immersed under stirring in at least one member selected from the group consisting of an acid, an acid solution and hot water which is at a temperature of 100.degree. C. or higher for a time sufficient to improved its affinity with said olefinic copolymer (B).
A polyphenylene sulfide resin composition comprising:
