Abstract: The performance comparison test among Luhua isoprene rubber, Russia 5PM, Russia 3S, Japan IR2200 and other isoprene rubber were carried on. The results show that the cis-1,4 content（higher than 96%）, the average molecular and its distribution（Mw/Mn is around 2）, glass transition temperature, trace elements, ash, volatile and other physical property data of domestic isoprene rubber are similar to the imported one. What is more, its blending and curing performance are consistent with the imported isoprene rubber. The domestic isoprene rubber can replace the import one used for the rubber products, especially for the health and medical products.

摘要： 进行了鲁华异戊橡胶与俄罗斯5PM、俄罗斯3S、日本IR2200等异戊橡胶的性能对比测试。结果表明，国产异戊橡胶的顺-1，4含量（大于96%）、平均分子质量及分布（Mw/Mn为2左右）、玻璃化转变温度、微量元素含量、灰分、挥发分等物性数据与进口异戊橡胶基本相近，其共混及硫化等使用性能与进口异戊橡胶基本一致。国产异戊橡胶可以替代进口异戊橡胶用于橡胶制品，尤其适用于卫生及医疗制品。
