In this study, waste rubber powder (WRP) was devulcanized by ultrasonic in alkaline medium and blended with the different ratios of EPDM/PP and the coupling agent of dicumyl peroxide (DCP) to produce WRD/EPDM/PP polymer blends. With the concentration of 10 wt.% (by weight) WRP gived the mechanical properties of blends before and after accelerated weathering testing were approxiated with those of EPDM/PP 30/70 blends. The presence of DCP improved the tensile at strength and thermal resistance, caused by interaction beetwen EPDM and PP. The results of thermogravimetric analysis showed that the presence of 0.5 %DCP gaved the maximum thermal resistance of polymer blends up to 380°C.
