| Abstract: |
| The coordinated control of melting recation and decomposing recation of insoluble sulfur（IS） during the compound mixing was studied.The result of DSC analysis showed that the fastest melting rate of IS was 124.0 ℃，and the fastest decomposing rate of sulfur was 132.9 ℃.The HAAKE rheology instrument was used to simulate the compound mixing process.When in wall of the rheology instrument（temperature at mixing start） was 90～95 °C，IS of natural rubber/IS blend did not decompose，and was dispersed very well. |
