　　对采用熔融共混法制备的PP/POE/LLDPE三元复合材料的力学及物理性能进行了测试研究，结果表明：三元复合材料较PP/POE复合材料具有较高的拉伸强度、杨氏模量、冲击韧性和透光率；PP/POE/LLDPE配比为90/10/5的三元共混体系具有最佳的力学性能和透光性，随着LLDPE含量的增加，三元复合材料的屈服应变、断裂伸长率、冲击韧性和透光率逐渐减小，拉伸强度和杨氏模量依次增大。

The mechanical and physical properties of PP /POE/LLDPE ternary composites prepared by using the melt blending method were studied in this paper .The results showed that the tensile strength, Young’s modulus, the impact toughness and the trans-mittance for the ternary composites are were greater than that of PP /POE composite.When the ratio of PP∶POE∶LLDPE was 90∶10∶5 the composite exhibited the best mechanical and transmittance properties .With an increase in LLDPE content the yield strain, the elon-gation at break, the impact toughness and the transmittance of the ternary composites decreased gradually , whereas their tensile strength, and Young's modulus increased in turn and continuously .
