English Abstract

A copolymer EPDM-g-GMA was prepared by grafting glycidyl methacrylate (GMA) onto EPDM in a torsion rheometer, then the EPDM-g-GMA obtained was blended with PP in a double screw extruder. The grafting rate of EPDM-g-GMA copolymer was determined by turn over titration measure, while the grafted EPDM-g-GMA copolymer was characterized by FTIR measurements. The morphology and mechanical properties of PP blended with EPDM-g-GMA was studied. It is found that with the increase of the EPDM-g-GMA content or the increase of temperature, the izod notch impact strength became higher, however, the tensile strength became lower. The results show that there is a correlation between the brittle-ductile transition temperature and the elongation at breakage of the PP/EPDM-g-GMA blend with the EPDM-g-GMA content.
