Abstract
Effect of chlorinated polyethylene(cPE) on the morphology and mechanical properties of isotactic polypropylene(iPP) and nitrile rubber(NBR) blends was investigated. It was found that incorporation of a small amounts of cPE leads to a decrease in domain size of the dispersed phase, and uniform distribution of the dispersed phase in the blends. The PP/NBR/cPE ternary blends showed an improved tensile and tear strength as well as elongation-at-break as compared to binary PP/NBR blends. From the results on morphology and mechanical properties, optimum amount of the cPE is 5-10 wt% with repect to NBR in the blend.
