| Abstract: |
| The structure and properties of Yanshan Branch rare earth polyisoprene rubber (YS-NdIR） and Russian titanium polyisoprene rubber(SKI-3） were compared，and the properties of compounds with YS-NdIR instead of equivalent NR were investigated.The results showed that，the YS-NdIR possessed higher mass fraction of cis-1，4-units and molecular weight，and better physical properties.The comprehensive properties of YS-NdIR compound and Russian SKI-3 compound were equivalent.The compound of YS-NdIR instead of equivalent NR had good processability，physical properties and dynamic mechanical properties. |
