ABSTRACT:
A vulcanizable polyacrylate elastomer composition having improved resistance to hydrocarbon oils is provided which comprises one or more lower alkyl acrylic acid ester monomers polymerized with a comonomer containing either a halogen or an epoxy group, in the presence of from about 0.25 to 10 percent, by weight of total monomer, of a low molecular weight, unsaturated polymer of butadiene or isoprene or copolymers thereof with styrene or acrylonitrile. In addition, a process for preparing such elastomer compositions is also provided, together with the vulcanization of such elastomers and the resulting vulcanized polyacrylate.
