| Abstract: |
| The physical properties and dynamic property of NR reinforced by in-situ grafted carbon black were investigated，and the structure of compound was characterized and analyzed by using FTIR，TG and torque rheometer.The results showed that，when carbon black was in-situ grafted，the interaction between carbon black and NR was strengthened，the properties of vulcanizate were improved；the comprehensive performance of vulcanizate was the best when the addition level of modifier was 4.5 phr；the modifier was grafted onto NR and carbon black，and participated in the vulcanization. |
