| 摘 要： | 分析了不同的助交联剂对过氧化物硫化聚丙烯／乙烯-丙烯-二烯共聚物（EPDM）热塑性弹性体力学性能、流变性能、热稳定性能的影响，结果表明：不同的助交联剂均有提高凝胶含量和改善聚丙烯（PP）降解程度、提高力学性能的用途。其中，三羟甲基丙烷二烯丙基醚（TMPDE）作为过氧化物硫化PP／EPDM的助交联剂，相比三烯丙基异氰脲酸酯（TAIC）、邻苯二甲酸二烯丙酯（DAP）和三羟甲基丙烷三丙烯酸酯（TMPTA），所得制品综合力学性能优异，热稳定性能提高，流动性改善，微观结构均匀。

| Abstract: | The effect of co-crosslinker on the physical, rheological and heat stability properties of peroxide dynamically vulcanized PP/EPDM elastomers was studied. It was showed that all of the co-crosslinker increased the gel content, inhibited the degradation of PP, and improved the mechanical properties of PP/EPDM. Compared among the systems using TMPTA, DAP, and TAIC, the one using TMPDE exhibited better mechanical properties, higher flow ability, and more uniform microstructure than the other two. |
