合成并表征了马来酸酐/3-十五碳烯基苯基缩水甘油醚（GPPE）的交联物（M-GPPE），研究了其对三元乙丙橡胶/炭黑/白炭黑复合材料硫化特性、力学性能、动态力学性能和填料分散性的影响。结果表明，M-GPPE分子链上存在酸酐等活性基团，热稳定性比GPPE高；GPEE在复合材料中主要起增塑剂作用，并且可延缓硫化时间；在复合材料中加入6份（质量） M-GPPE可使其最小转矩下降，焦烧时间和正硫化时间缩短，拉伸强度和撕裂强度分别提高35％和8％，在40～70℃具有较高的损耗值；透射电镜的分析表明M-GPPE可改善填料在基质中的分散性，减少了白炭黑的团聚。

A cross-linked polymer(M-GPPE) was synthesized by maleic anhydride and glycidyl 3-pen-tadecenyl phenyl ether ( GPPE) , and the structure of the obtained product was characterized.The effects of M-GPPE amount on cure characteristics , mechan-ical and dynamic mechanical properties , and filler dispersity of ethylene propylene diene monomer ( EPDM)/carbon black/silica composite were studied.The results showed that the presence of some active groups , such as anhydride group , in the molecular chain of M-GPPE resulted in higher ther-mal stability of M-GPPE than GPPE.GPPE played the role of a plasticizer in EPDM composite , thus extending curing time.The addition of 6 phr M-GPPE led to lower minimum torque , shorter scorch time and curing time as well as higher damp-ing value of the composite.The tensile strength and tear strength of the composite with 6 phr M-GPPE were increased by 35% and 8%, respectively.Transmission electron microscope analysis indicated that the dispersion of the filler in matrix was im-proved by M-GPPE, which reduced agglomeration of silica.
