OIL RESISTANT THERMOPLASTIC ELASTOMER COMPOSITION AND PRODUCTION THEREOF

摘要

The present invention provides a process to prepare an oil resistant thermoplastic elastomer composition which contains carboxylated nitrile rubber, polyvinyl chloride and polycaprolactone. The process requires the use of a peroxy curing agent and a coagent. The resulting composition has excellent melt flow index, is oil resistant and further exhibits surprising rubbery properties such as tensile strength and limited compression set.
