| Abstract: |
| The effect of vulcanization on multiple interactions in carbon black （CB） filled SBR was investigated by means of MDR， RPA and DMA.The results showed that the CB aggregates agglo merated at the initial stage of vulcanization.It was found that when the addition level of CB reached a certain value，the reinforcement effect of CB on the compounds was better than the vulcanizates，and the reinforcement effect was significantly affected by strain sweep.Payne effect was related to the CB volume concentration.The increase of glass transition temperature（Tg）of the compounds with increase of CB volume concentration was larger than that of the vulcanizates.The difference of Tg of unfilled system before and after vulcanization was larger than that of filled system.The Tg and bound rubber content increased linearly with the increase of CB content. |
