Metal-Free Cationic Ring Opening Polymerization of Glycidol: Structure Control of Polymer Topologies and Terminal groups |
| 초록 |
Metal-free cationic ring opening polymerization (CROP) system was investigated using tris-(pentafluorophenyl)borane (B(C6F5)3) as a catalyst and glycidol (GD) as a monomer to give branched polyglycidol (PGD) under mild polymerization condition. This metal-free CROP system provides scalable synthesis of PGD and rapid polymerization under ambient condition. Further development of this facile metal-free CROP system was then expanded to the structure control of polymer topologies and terminal groups using base additives. The structural changes of resultant PGD were characterized by inverse-gated 13C NMR and showed significant differences such as degree of branching (DB), linear units (L 1,3 and L 1,4), dendritic unit (D), and terminal groups (T 1 and T 2). |
