 Blends reinforced by (30,50, and 70%) PVC were studied in this paper. The results from this work show that the strength will impairment after immersion in oil and water as a result of the penetration of the oil and water molecules within NBR-PVC blend, which increase the extending between the main chains and cause the weakening in secondary forces of (vander walls) and crosslink so that the Brownian motion of molecular chains will increases Which leads to a decrease in hardness.&picture=http://www.aascit.org/aascit/decorators/img/journal/916.jpg)

Polymer blends are capable of providing materials with extended useful properties beyond the range that can be obtained from single polymer equivalents. Effect of immersion in oil and water on hardness of Acrylonitrile butadiene rubber (NBR) Blends reinforced by (30,50, and 70%) PVC were studied in this paper. The results from this work show that the strength will impairment after immersion in oil and water as a result of the penetration of the oil and water molecules within NBR-PVC blend, which increase the extending between the main chains and cause the weakening in secondary forces of (vander walls) and crosslink so that the Brownian motion of molecular chains will increases Which leads to a decrease in hardness.
