| Abstract: |
| The effect of the reversion on the structure and properties of NR vulcanizate was investigated.The crosslink density and distribution of NR vulcanizate were determined during the reversion by the devulcanization with the chemical probes.The test results were in accordance with the mechanism of NR cure and reversion.The physical properties of NR vulcanizate with the cure time at different temperatures，as well as its dynamic properties during cure and reversion were determined.The results showed that the dy namic heat build-up resulted in the reversion，which led the increase of loss modulus and the premature failure of tire. |
