ABSTRACT:
A polymer composition is provided comprising at least one poly(arylene sulfide), at least one polysiloxane, at least one trialkoxysilane, and at least one solid, resinous polyolefin. Molded objects made of this polymer composition have greater impact strength than those made of poly(arylene sulfide), preferably poly(phenylene sulfide). In one embodiment, an additive composition comprising at least one polysiloxane, at least one trialkoxysilane and at least one solid, resinous polyolefin is provided. The additives can be blended with poly(arylene sulfide) so as to improve its impact strength. In another embodiment, a polymer composition is provided comprising at least one poly(arylene sulfide), at least one polysiloxane having molecular in the range of from about 100,000 to about 4000,000, and optionally at least one trialkoxysilane.
