Abstract
A number of new ionic vinyl monomers composed of 1�vinylimidazolium cation with diethoxy� and dihydroxyphosphoryl groups and various anions—Br - , (CN)2N - , and (CF3SO2)2N - —are synthesized. The freeradical polymerization of the monomers in solutions of molecular and ionic solvents yields new polymer analogs of ionic liquids, and their molecularmass characteristics, solubility, heat resistance, thermal stability, and electrical conductivity are estimated. It is shown that the incorporation of bulky phosphorylalkyl side substituents into the vinylimidazolium polycation causes a decrease in the glasstransition temperature and an increase in the ionic conductivity of polymer salts. The highest ionic conductivity (2.6 × 10 -5 S/cm at 25°C) is exhibited by the polymer with the (CN)2N - anion.
