A method of synthesis of protic anion-active hyperbranched oligomeric ionic liquid based on hyperbranched polyester polyol of the second generation is developed. The chemical structure of the compound is studied by IR and 1H NMR spectroscopies. The glass transition temperature of the obtained compound is − 9.2 ºC, and the beginning of its thermal oxidative degradation is 270 ºC. The ionic conductivity of the synthesized oligomeric ionic liquid is characterized by the values of 6.44 · 10−5 S/cm at 20 ºC and 3.22 · 10−3 S/cm at 100 ºC in anhydrous medium.
