Anionic Synthesis of Chain-end Functionalized Polymer by Bipyridine |
| 초록 |
Functionalization reactions of Poly(styryl)lithium and Poly(butadienyl)lithium(Mn = 1~2Ⅹ103 g/mol) with dipyridylketone in cyclohexane. The functionalization yield depend on varying the mode of addition of dipyridylketone but the stoichiometry of reactants, the reaction temperature and solvent are not effective for fucnctionalization yield. The functionalization yield of polybutadiene is approximately 80~90%. The functionalized polymers were investigated by 1H-NMR, 13C-NMR spectroscopy and FT-IR spectroscopy. Molecular weight distributions were measured using Gel Permeation Chromatography(GPC). |
