摘　　要：采用动态硫化法制备了POE/PP(乙烯-辛烯共聚物/聚丙烯)共混型热塑性弹性体,考察了不同投料方式对POE/PP体系的加工流变性、力学性能、交联程度等的影响。结果表明,优化投料顺序能有效抑制PP的降解作用,使体系性能得到改善,投料方式对POE/PP体系的相容性影响显著。当POE相尺寸较小且分布均匀时,体系的力学性能提高。The POE/PP blends were prepared by using dynamic vulcanizing process. The macroscopic and microscopic properties about processing theological characterisitic, mechani cal properties and the degree of crosslinking were investigated via changing the feeding methods. The results show that the degradation of PP can be effectively controlled by optimum feeding and the system properties are improved. The compatibility of POE/PP is effected by the feeding methods. The mechanical properties are improved when POE phase size is small and homogeneous distribution.
