<p>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.</p> |
