The work is devoted to the development of scientific foundations for the production of polymeric ionic liquids and ionic liquids of ionen type based on morpholine with high ion conductivity in a wide range of temperatures. Established the dependencies of their physic-chemical properties on structure and external factors (solvent, temperature, etc.) for solving urgent macromolecular chemistry problems.Ion conductivity, its increases with decreasing of anion size, melting point (glass transition), and molecular mass of ionic liquids.The melting point (glass transition) of polymeric ionic liquids and ionic liquids of ionen type decreases with decreasing anion size and molecular weight. It was established that the new polymeric ionic liquids and water morpholine-based liquids have a significantly higher level (four to fifteen orders) of ionic conductivity (~ 10–1–10–6 Sm·cm–1) without properties changing in temperature range –280С ÷ –1350С in comparison with the world known analogues on the basis of polymeric ionic liquids.
