| Abstract: |
| The properties of domestic environment-friendly oil extended SBR1739 were studied，and compared with imported products.The results showed that，domestic SBR1739 possessed a little higher oil content，lower glass transition temperature，and better processability.Its mix also possessed better processing safety，lower curing rate，and thus needed higher extrusion temperature.Its vulcanizate showed higher elasticity，lower rolling resistance，and excellent wet skid resistance.To improve the extrusion property，the content of higher molecular weight part of SBR1739 needed to be properly reduced. |
