中文摘要:
      采用双螺杆挤出机制备茂金属聚烯烃弹性体(POE)/聚丙烯（PP）热塑性硫化胶（TPV），考察硫化剂双25用量、助硫化剂TAIC用量和POE/PP共混比对TPV微观结构、动态力学性能、物理性能和耐热空气老化性能的影响。结果表明，硫化剂双25用量为2份、助硫化剂TAIC用量为5份、POE/PP共混比为60/40～70/30时，在保证POE/PP TPV顺利挤出的前提下，POE/PP TPV的综合性能较优。
英文摘要:
      The metallocene POE/PP TPV was prepared by twin screw extruder，the effects of addition level of curing agent 2，5-dimethyl-2，5-dilbuty(peroxy) hexane（DHBP），addition level of secondary curing agent TAIC and blending ratio of POE/PP on the microstructure，dynamic property，physical properties and thermal air aging property of TPV were investigated.The results showed that，under the premise of ensuring complete smooth extrusion，the comprehensive properties of POE/PP TPV were better when the addition level of DHBP was 2 phr，the addition level of TAIC was 5 phr and the blending ratio of POE/PP was 60/40～70/30.
