| Abstract: |
| The properties of different kinds of IR were compared.The results showed that，the physical properties of all IR compounds were equivalent and the dynamic mechanical property of Yanshan branch titanium polyisoprene（YS-TiIR） was more balanced.By using IR instead of equivalent NR in tread compound of truck tire，the comprehensive properties of YS-TiIR compound and Russian SKI-3 compound were mainly equivalent，and with 30 phr titanium polyisoprene instead of equivalent NR，the processability and physical properties of compound had minimum change. |
