Toughened polyphenylene sulfide compositions are provided having impact strength weld line strength and tensile elongation among other advantages. The compositions include a blend of polyhenylene sulfide and an olefin terpolymer for toughening the polphenylene sulfide. The terpolymer has the formula E/X/Y (I), where E is an olefinic polymer, X is an acrylic ester and Y is a glycidyl ester. The compositions may also include reinforcing agents or fillers, preferably glass fibers or carbon fibers. The compositions are formed by blending polyphenylene sulfide and an olefin terpolymer of formula (I), with no acid, hot water or organic solvent wash pretreatment of the polyphenylene sulfide.
