| Abstract: |
| NR/BIIR and NR/BR/BIIR blends were prepared and the physical properties，heat air aging resistance and dynamic mechanical properties of the blends were investigated. The results showed that，compared with the compound without BIIR，the physical properties of therespective blend with BIIR decreased slightly，the hot air aging resistance increased significantly，the wet-skid resistance was improved，and the rolling resistance changed little. When the BIIR amounts in the NR/BIIR and NR/BR/BIIR blends were 10 and 15 phr，respectively，the heat air aging resistance of the blends were excellent. |
