Some properties of polymer blends based on EPDM/PP

This work describes the effect of the addition of EPDM to polypropylene on the mechanical performance of EPDM/PP blends prepared in different composition ranges and mixing conditions, and evaluates the effect on the mechanical properties when controlled degraded polypropylene is added to these blends as a third component. It was found that as the EPDM content increased, the impact strength of EPDM/PP blends increased; the tensile strength and Young's modulus decreased and the elongation increased but showed a slight decrease at 5050 composition.
