Hyperbranched polymer was synthesized from pentaerythritol (as the central core), 1,2,4‐trimellitic anhydride, and epichlorohydrin, and then hyperbranched polymer electrolytes with terminal ionic groups were prepared by the reaction of hyperbranched polymer with N ‐methyl imidazole. The chemical structure, thermal behavior, and ionic conductive property of the hyperbranched polymer electrolytes were investigated by 1 H‐NMR, FTIR, differential scanning calorimetry, thermogravimetric analyzer, and complex impedance analysis, respectively. The ionic conductivity of hyperbranched polymer electrolyte was up to 2.4 × 10 −4 S cm −1 at 30°C. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
