| 中文摘要: |
| 研究中国石化北京化工研究院燕山分院稀土异戊橡胶(YS-NdIR）的结构和性能并与俄罗斯钛系异戊橡胶进行对比，采用YS-NdIR等量替代天然橡胶(NR）进行试验。结果表明：YS-NdIR具有较高的顺式1，4-结构质量分数和相对分子质量，有利于应变诱导结晶，物理性能较好，其综合性能达到国外同类产品水平。与NR胶料相比，采用YS-NdIR等量替代NR后的胶料具有较好的加工性能，保持了良好的物理性能和动态力学性能。 |
| 英文摘要: |
| 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. |
