ABSTRACT:
A curable polymeric composition exhibiting good low temperature flexibility comprising about 50-90 parts by weight chlorinated polyethylene or chlorosulfonated polyethylene containing about 30-45 weight percent chlorine, and about 10-50 parts by weight of an ethylene terpolymer of 48-74 weight percent ethylene, 20-40 weight percent alkyl acrylate wherein the alkyl group contains 4-9 carbon atoms, and 6-12 weight percent carbon monoxide or sulfur dioxide. Such polymeric blends are especially useful for low temperature applications in contact with oil, e.g. automotive seals and hoses.
