| Abstract: |
| 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. |
