Abstract
A polyarylene sulfide resin composition having improved toughness and impact resistance is formed by 100 wt. parts of polyarylene sulfide and 0.5-50 wt. parts of a graft copolymer. The graft copolymer includes an olefin copolymer segment comprising .alpha.-olefin units and .alpha.,.beta.-unsaturated acid glycidyl ester units, and a grafting polymer segment comprising .alpha.,.beta.-unsaturated acid glycidyl ester units and chemically bonded to the olefin copolymer segment. The .alpha.-olefin is preferably ethylene. The .alpha.,.beta.-unsaturated acid glycidyl ester is preferably glycidyl acrylate or glycidyl methacrylate. The grafting polymer segment is preferably in the form of a copolymer of an .alpha.,.beta.-unsaturated acid glycidyl ester and a monoethylenically unsaturated monomer.
