Abstract
The melting-grafting of maleic anhydride ( MAH ) onto ethylene-octene copolymer ( EPDM ) through adding a certain initiator and increasing the screw rotation speed were investigated,and the graft prod-ucts were used to improve the mechanical properties of polypropylene or with calcium carbonate. The grafting level and the melt flow rate were studied by titration analysis,FT-IR and determination of melt flow rate at 175 degrees centigrade. The mechanical properties and the heat distortion temperature of polypropylene composites were discussed. The results showed that the notched impact strength of PP/EPDM-g-MAH blends was 9. 85 kJ/m2 and 1. 97 times of pure PP when the content of elastomer was 30phr,the thermal deformation temperature of PP/EPDM-g-MAH showed a downward trend;the notched impact strength of PP/EPDM-g-MAH/CaCO3 whisker ternary composites was better than that of PP/EPDM-g-MAH blends,which was 12. 94kJ/m2 and 2. 59 times of pure PP when the content of CaCO3 whisker was 20 phr, the thermal deformation temperature of the blend system was the best.关键词
