| Abstract: |
| Compared with BIIR，the properties of BIIR/NR，BIIR/BR，BIIR/SBR blends were studied. The results showed that，the processability of BIIR/NR blend was the best，meanwhile the cure characteristics，physical properties and gas-tightness of BIIR/NR blend were good.The crosslinking density of BIIR/BR blend was the highest，and the chang of die swell ratio was the most insensitive with shear rate.BIIR/SBR blend also had good processability，and its scorch time and curing time were the longest，it had excellent physical property retention after thermal aging，and its die swell ratio at low shear rate was the minimum. |
