| Abstract: |
| The properties of trans-1，4-polyisoprene (TPI)/high vinyl poly butadiene (HVBR) blends，especially the balance among rolling resistance，heat build-up and wet traction were investigated.The results showed that the wet traction of TPI improved greatly by blending with HVBR；tanδδ at 0 ℃ of TPI/HVBR with blending ratio of 60/40 increased nearly by three times when compared to that of TPI alone；and tanδat 0 ℃ increased by seven times when TPI/HVBR with blending ratio of 40/ 60 was used.The tanδ values at 60 and 80 ℃ of TPI/HVBR were lower than those of TPI respectively，thus the balance among rolling resistance，heat build-up and wet traction were obtained. |
