Abstract: The effects of POE, talc, EBS on the mechanical properties, melt flow index, crystallization temperature, thermal stability and fracture morphology of PP matrix composites were investigated. The incorporation of 25 phr POE into this PP resulted in a completely brittle-ductile transition. The composites achieved a melt flow index of 22.9 g/10 min, flexural modulus of 1887.7 MPa and notched impact strength of 31.2kJ/m2 at a PP/POE/talc weight ratio of 80∶20∶40. Compared to pure PP, the composites gained an increase in flexural modulus by 102.2 %, in notched impact strength by 217.8 % and flexural strength by 2.6 %, and however they showed a decrease in tensile strength by 15.1 %. Both the melt index and notched impact strength of the composites tended to increase with the addition of 1phr EBS.
