| Abstract: | 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 content of 1,4-structure and narrow molecular-weight distribution. The degree of functionality approached 2. |
