Abstract
Abstract A composition and method for forming the composition providing a molding composition of poly(arylene sulfide) and a crack resistance and/or an impact strength improving amount of a polymeric rubber chosen from among silicone rubber, ethylene-acrylic rubber, ethylene-propylene rubber, ethylene-propylene-diene rubber, and poly(butyl acrylate) rubber. In embodiments of the invention the improvement is enhanced by the addition of organosilane to the composition.
