| Abstract: |
| The influence of molecular weight and structure of SSBR on the interface and physical properties of silica/SSBR composite was investigated.The results showed that the content of bound rubber increased as the molecular weight and molecular chain length increased；when the bound rubber content increased，the filler-network was weakened，filler distribution was improved，interaction between filler and rubber was enhanced，and the physical properties of vulcanizate were improved；the abrasive resistance of composite didnt show direct relationship to the content of bound rubber，and the abrasive resistance was increased as the interaction between filler and rubber was enhanced. |
