A composition obtained by adding at least one specific elastomer and optionally a polyamide resin or a bromine-containing flame retardant to a melt-kneaded product of a polyphenylene sulfide with a non-blocked type polyfunctional isocyanate compound. The composition is excellent not only in impact resistance but also in aging resistance at high temperatures. Said composition can be advantageously used for molding parts of automobile engines, parts for various machines, connectors for electric or electronic parts, bobbines and the like.
