Abstract
New regularities have been discovered in the synthesis of polymer ionic liquids and ionene-type ionic liquids based on polyionenes derived from tetrahydro-1,4-oxazine. The methods for regulating the molecular weight of the synthesized polymers have been improved by varying the nature and composition of the solvent, as well as the concentration of the starting monomers. These improvements have resulted in the creation of new and promising materials. For the first time, we investigated the effects of temperature, solvent type and composition, chemical structure, and concentration of polyionenes derived from tetrahydro-1,4-oxazine on their behavior in water and water-ethanol solutions, as well as the shape of macromolecules in different solvents. Newly synthesized polymeric ionic liquids and ionene ionic liquids with an ionic conductivity of 10–2–10–5 S•cm–1 and a glass transition temperature range of –1500С–150С exhibit five to six orders of magnitude higher ionic conductivity compared to known analogues.
