| Abstract: |
| The comprehensive physical properties and dynamic mechanical properties of TPI/HVBR/NR （trans-1，4-polyisoprene/high vinyl polybutadiene）blends were investigated.The results showed thatthe lower rolling resistance and heat build-up were obtained and the wet traction improved significantly when 70 phr of NR and 10～20 phr of HVBR were used in the TPI/HVBR/NR blend；tanδat 0 ℃ of the blend increased by 42.2% and tanδat 60 and 80 ℃ decreased somewhat when 20 phr of HVBR were used；and the TPI/HVBR/NR blend with 70～50 phr of NR，10～25 phr of TPI and 20～35 phr of HVBR possessed not only better comprehensive physical properties，but also lower rolling resistance and higher wettraction，and was an ideal tread compound. |
