ACRYLIC RUBBER COMPOSITION, MOLDED BODY, AND AUTOMOBILE/ELECTRICAL/ELECTRONIC COMPONENT

摘要

Disclosed is an acrylic rubber composition containing a polyorganosiloxane-containing graft copolymer having excellent powder characteristics. This acrylic rubber composition is excellent in mechanical characteristics, heat resistance and oil resistance while exhibiting adequate mold releasability during a molding process. Specifically disclosed is an acrylic rubber composition containing an acrylic rubber (A) and a polyorganosiloxane-containing graft copolymer (B), which is characterized in that the component (B) is a copolymer of a polyorganosiloxane (d1) and a graft component, and the graft component (with (b-1) + (b-2) + (b-3) being 100%) is composed of 50-95% by weight of an aromatic vinyl monomer (b-1), 50-5% by weight of a vinyl cyanide monomer (b-2) and 0-30% by weight of a vinyl monomer (b-3) which is copolymerizable with the components (b-1) and (b-2). Also disclosed are a molded body obtained from such a composition, and an automobile component and electrical/electronic component comprising such a molded body.
