中文摘要:
      采用转矩流变仪研究环氧化反式1,4-聚异戊二烯(ETPI)的塑炼行为及其在塑炼过程中的老化降解行为。结果表明:随着环氧度的提高,ETPI达到塑化点的时间缩短,较高环氧度的ETPI的塑炼行为对温度更为敏感。ETPI在塑炼过程中发生明显的副反应,生成醇及呋喃环结构,且环氧度越高,副反应越严重。ETPI在塑炼前期,首先发生交联反应,进而发生交联键的断裂引起凝胶质量分数减小。
英文摘要:
      The plastication behavior and aging degradation of epoxidized trans-1,4-polyisoprene (ETPI) were investigated by using torque rheometer.The results showed that,as the epoxy content increased,the plastication started earlier.The plastication behavior of ETPI with higher epoxy content showed higher sensitivity to temperature.The side reaction of ETPI occurred during plastication,which produced alcohol and furan ring structure.The side reaction became more severe as the epoxy content increased.In the beginning of the plastication process,the cross-linking reaction occurred at first,and then the cross-linking bonds were broken which reduced the gel content.
