摘要: Hyperbranched poly(glycidol) containing hydroxyl groups was firstly synthesized via anionic polymerization and then reacted with 2-bromoisobutyl bromide to form macroinitiator HPG-Br. Finally, a hyperbranched star polymer (HPG-PPEGMA) successfully prepared by atom transfer radical (ATRP) of poly(ethylene glycol) methyl ether methacrylate using HPG-Br as macroinitiator. The structures properties the obtained polymers were characterized 1H NMR, attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), differential scanning calorimetry (DSC), X-ray diffraction (XRD), thermogravimetric analysis (TGA). ionic conductivity electrolytes composed HPG-PPEGMA lithium bis(trifluoromethanesulfonimide) (LiTFSI) investigated electrochemical impedance spectroscopy. results showed that room temperature had higher conductivity. When [EO]/[Li] 20, electrolyte up 1 × 10−4 Scm−1 at 30 °C. onset decomposition polyether could reach 374 °C, indicating good thermal stability. XRD structure beneficial improve due possessing low degree crystallinity.
