Abstract

A research aim to improving the swelling resistance of Nitril rubber NBR by insertion a various amounts of Polyvinyl chloride PVC,(30% ,50% and 70% ) respectively, at curing condition (temperature 170 C, pressure 90 bar during 20 min) that leads to create a new polymer morphology of polymer blend. Swelling resistance in the oil and distilled water exponentially improved with increasing PVC content in blend, weather resistance and thermal stability of NBR is also developed with PVC addition due to PVC have higher glass transition temperature which 87 C than NBR which is -15 C.
