| Abstract: |
| The dynamic mechanical properties of IIR/resin curative blend system were investigated.It was found by DSC and DMA that IIR was quite compatible to resin curative.The test results of dynamic mechanical properties showed that the DMA curve of IIR/resin curative blend system shifted to the region of high temperature as the level of resin curative increased，and the temperature region for damping change of blend system could be changed by adjusting the level of resin curative；and the maximum tanδ of blend system decreased at first，increased to a peak later，and then decreased rapidly as the level of resin curative increased. |
