摘　　要：用熔融共混法制得了聚烯烃类弹性体（POE）／PP共混体系，研究了不同橡塑比对体系力学性能的影响；考察了不同填料（CaCO3，滑石粉．炭黑）对POE／PP复合材料性能的影响。结果表明：在共混比为60／40-70／30时，体系的综合性能较佳。加入的填料均使材料的拉伸强度和拉断伸长率下降，硬度上升。The POE/PP composite was made through melt blending. The effect of the ratio of rubber and plastics, as well as different fillers （CaCO3, talcum powder, carbon black） on mechanical properties of POE/PP was studied. The results showed that the optimal mechanical properties of POE/PP was obtained when the rate of rubber and plastics was between 60/40 and 70/30. The tensile strength and elongation at break were decreased with increasing the loading of the fillers while the hardness was increased.
