| Abstract: |
| The curing behavior，physical properties and dynamic mechanical property of NR/BR/1，2-polybutadiene rubber (1，2-PBR） blends were studied，and the optimum blending ratio of BR/1，2-PBR was obtained.The results showed that，compared with those of NR or BR，the processability of 1，2-PBR was poor.As the blending ratio of BR/1，2-PBR was 25/5，the NR/BR/1，2-PBR blend possessed better comprehensive physical properties and wet skid resistance.When the BR/1，2-PBR blending ratio was 15/15，the blend had lower compression temperature rise，lower compression set，and good mechanical property.The blend with BR/1，2-PBR blending ratio at 15/15 was more suitable for tire tread. |
