摘　　要：研究了不同润滑剂对PP/POE(聚丙烯/聚烯烃弹性体)性能的影响。结果表明,硬脂酸类润滑剂对PP/POE的拉伸强度影响不大,硬酯酸盐类润滑剂对PP/POE冲击强度影响不大。硬脂酸类以及非硬脂酸类润滑剂对PP/POE的弯曲模量、热变形温度均有一定的影响。润滑剂一定程度上提高了PP/POE的加工性能,润滑剂在静态以及动态的加工条件下起到的作用是不同的。硬脂酸盐类有利于PP/POE的结晶。The influences of various lubricants on properties of polypropylene/polyolefin elastomer（PP/POE） were investigated. The results show that stearic acid type lubricants have little effect on tensile strength and stearate type lubricants have little effect on impact strength. Stearic acid type and non-stearic acid type lubricants have some effect on flexural module and heat deformation temperature. The process property can be improved by using whatever lubricants. The effects of lubricants on static and dynamic process are different. The crystalline properties of PP/POE are improved by the use of stearate type lubricants.
