The morphological properties of PP/EPDM/NR blends were investigated. A double layered morphological structure was observed for the compression moulded PP/EPDM/NR blends. Blends with low levels of elastomer content show a particulate distribution in the elastomer phase. For the 80/10/10 blend an interpenetrating co-continuous network is observed. The same blend shows the highest impact strength.
