| Abstract: |
| The structure and properties of NR/BR/NBR blend were investigated.It was found through the analysis by TEM that as the proportion of NBR increased，the distribution of carbon black tended to more even；two glass transition temperatures existed in the blend；the tanδat 0 ℃ increased greatly and the tanδat 65 and 80 ℃ decreased at first and then increased in a small range；and the physical properties of blend changed little.A new type of tread compound based on NR/BR/NBR with good wet traction，low rolling resistance and low heat build-up could be obtained by adjusting the proportion of NBR in the blend. |
