Ionic Liquids (ILs) are design solvents for free radical polymerization and preparation of composite materials! There is NO general rule for choosing of ionic solvent, but by means of design it is possible to select the best one for a concrete process. CF3SO3 and CF3COO based ILs provide the formation of highest molecular weight polyacrylonitrile (PAN, Mn≈8.8 × 105) and polymethylmethacrylate (PMMA, Mw≈18.9 × 105) in a quantitative yield (PAN – 96%, PMMA – 92%). (CF3CF2)3PF3 ILs promote the formation of high molecular weight PMMA even upon the polymerization under the atmospheric pressure with the presence of air oxygen. Nature of the IL stongly influences the properties of the resulted composites films, namely, their flexibility, transparency and surface morphology. Composite films derived from PAN and B(CN)4 ionic liquids possess ionic conductivity as high as 1.0 × 10−2 S cm−1 at 25°C.
