Synthesis of 1,2,3-triazole-embeded copolyether polyol using Azide-Alkyne "Click" Functionalization |
| 초록 |
Novel synthetic methodology for the 1,2,3-triazole-embedded copolyether polyol was provided by the wide spectrum of azide-alkyne "Click" chemistry. 1,2,3-Triazole-embedded polyetherdiol could be synthesized by Copper-catalyzed 1,3-dipolar cycloaddition using the Glycidyl azide polymer(GAP) and alkyne group containing triple bond at room temperature. The GAP or poly(GAP-co-THF) were converted easily with alkyne in high yield ＞95% in presence of TEA base to obtain the high viscous 1,2,3-triazole-embedded copolyrther polyol without any noticed change of difunctionality. The structure and the composition of synthesized copolymers have been characterized by 1H-NMR spectroscopy. The molecular weight distribution of their copolymer have been analyzed by gel-permeation chromatography(GPC). |
