本文采用保护基团引发剂法在环己烷溶剂中通过阴离子聚合合成双端羟基聚异戊二烯，并通过GPC、IR、1H NMR、羟值分析方法对其进行了表征。结果表明，聚合物有高的1,4-结构含量，同时聚合物的分子量大小可以控制、分子量分布窄、官能度接近2。

Hydroxyl-terminated Polyisoprenes were synthesized by anionic polymerization using novel protected-group initiators in the solvent of cyclohexane. The chemical structures were identified by GPC, IR, 1H NMR, and hydroxyl group content analysis technique. The obtained Hydroxyl-terminated Polyisoprenes showed high level of 1, 4-structure, narrow molecular-weight distribution. The degree of functionality approached 2.

Key words: protected group, anionic polymerization, hydroxyl-terminated polyisoprene
