The increasing environmental awareness has led to the search of alternative reaction media to alleviate or completely eliminate organic solvents use. Deep eutectic solvents (DESs), a subclass of ionic liquids, have emerged as sustainable solvents for a plethora of chemical reactions. In this talk, DES utilization in free-radical polymerizations will be presented and discussed. Two main fields of application are reported. In the first section, monomers able to undergo free-radical polymerization while taking part of DES, as hydrogen bond donor or ammonium salt, so called DES monomers, are presented. In the second section, the role of DES as solvent where the polymerization takes place, either in the same phase or emulsion, is described. Finally, the properties of the polymers resulting from these particular methods of synthesis are discussed with emphasis on their green aspects and the formation of nanocomposites.
