Direct Introduction of Hydroxyl Group in Polystyrene Chain-End Prepared by Atom Transfer Radical Polymerization |
| 초록 |
We report a method to directly introduce a hydroxyl group at the omega chain-end of polystyrene (PS) prepared by atom transfer radical polymerization. To achieve the quantitative conversion of the bromine group to a hydroxyl group, the transfer reaction of carbocation with water was exploited. The transfer reaction is a well-known reaction in cationic polymerization. The quantitative conversion and chemical structures of hydroxyl-terminated PS were characterized using 1H nuclear magnetic resonance (1H NMR), matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-ToF MS) and high-performance liquid chromatography (HPLC). In addition, various functional groups (acetonide and propane groups) can be introduced by the substitution of the bromine group in the PS using alcohol compounds based on the transfer reaction of carbocation. |
