Abstract

The effect of dynamic vulcanization on properties of PP/NBRr blends has been investigated. Natural weathering has been carried out for period of 3 months and 6 months. It has been observed that tensile properties and oil resistance of the blends improved by dynamic vulcanization. SEM results indicate that dynamic vulcanization can be employed as a technique to get finer and stable morphology of PP/NBRr blends. The natural weathering properties were investigated by means of tensile properties, surface morphology and FTIR analysis. The results showed that vulcanized PP/NBRr blends were able to withstand natural weathering better compared to unvulcanized PP/NBRr blends.
