THERMOPLASTIC ELASTOMER BLENDS OF A POLYVINYL CHLORIDE-ACRYLATE COPOLYMER AND CROSSLINKED ELASTOMERS

摘要

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 an effective amount of an elastomer. 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.
