Anionic polymerization is a method that can control molecular weight and molecular weight distribution. In this study, the polyisoprene(PI) was synthesized by anionic polymerization and it found that they have various microstructures which determined by solvent and temperature. In fact, PI having a high ratio of 1,2-/3,4-structure was synthesized by sec-butyllithium and tetrahydrofuran as initiator and solvent. Then, the synthesized PI was functionalized by using amine and benzyl thiol with radical initiator under mild conditions. As a result the physical properties and solubilities were changed dramatically after functionalization. |
