摘　　要：介绍了我国聚烯烃弹性体(POE)增韧聚丙烯(PP)用于汽车保险杠的研究情况,包括基体树脂的选择、POE的结构及特点、POE的种类和用量、无机填料的种类和用量对PP力学性能的影响。通过POE与其它增韧剂的对比,发现较少用量的POE就能显著改善共混体系和韧性,并对我国汽车保险杠的开发现状和未来发展趋势进行了讨论。Studies of employing POE for toughening PP to meet the demands of automobile bumpers are introduced.The choices of basic resins,the structure and features of POE and the influences of the dosages and types of POE,inorganic fillers on the mechanical properties of PP are discussed.Through the comparision of toughening effects between POE and other toughening agents,it can be seen that lower level addition of POE significantly improved the toughness of blends and the present developments and trends of automobile bumper in China are discussed.
