Abstract:
Thermoplastic elastomer blends containing polyvinyl chloride having improved oil resistance, exceptionally low compression set and softness are made by mixing a polyvinyl chloride-acrylate copolymer with effective amounts of cured acrylate elastomers. The polyvinyl chloride-acrylate copolymer has an inherent viscosity of from about 0. 3 to about 4. 0 and is made from a vinyl constituent which is a vinyl chloride monomer with an optional vinyl component comonomer and one or more acrylate monomers having the formula ##STR1## wherein R. sup. 1 is an aliphatic, an aromatic, or combinations thereof, having from 1 to 18 carbon atoms, or a halogen derivative thereof, or hydrogen, and R. sup. 2 is an aliphatic, an aromatic, an alkyl hydroxyl, or combinations thereof, having from 1 to 18 carbon atoms, or a halogen derivative thereof; or a hydrocarbyl ether such as an alkoxyalkyl, a phenoxyaryl, a phenoxyalkyl, or combinations thereof, having from 2 to 1,000 carbon atoms, or a substituted halogen, oxygen, sulfur, or nitrogen derivative thereof, and wherein the acrylate elastomer is made from one or more acrylate monomers having the formula ##STR2## wherein R. sup. 3 is an aliphatic, an aromatic, or combinations thereof, having from 1 to 18 carbon atoms, or a halogen derivative thereof, or hydrogen, and R. sup.
