Ionic Liquids as Novel Reaction Media for the Synthesis of Condensation Polymers

The use of ionic liquids as novel solvents for the synthesis of condensation polymers was investigated. A series of ionic liquids including new ones was synthesized and purified. 1,3-Dialkylimidazolium-based ionic liquids seem to be suitable reaction and activating media for the synthesis of high-molecular-weight aromatic polyimides and polyamides. Inherent viscosities of the polymers obtained in 1,3-dialkylimidazolium bromides range from 0.52 to 1.35 dL/g.
