| Abstract: |
| The properties of SSBR and ESBR tread compound filled with the same volume fraction of carbon black or silica were investigated.The test results showed that，compared with carbon black filled SBR compound，the dispersity of SBR compound filled with silica in-situ modified by coupling agent Si69（the amount was 8% of silica amount） was better，the modulus at 300% elongation of vulcanizate increased，and the elongation at break decreased，the wet skid resistance was improved，and the rolling resistance and dynamic temperature rise decreased，but the abrasion resistance and cut-resistance were poor. |
