About

The Instituto de Ciencia de Materiales de Madrid (ICMM) is an institute of the Consejo Superior de Investigaciones Cientificas (CSIC) (Spanish National Research Council) founded in December 1986, that belongs to the Area of Science and Technology of Materials, one of the eight Areas in which the CSIC divides its research activities.

 

Our mission is to create new fundamental and applied knowledge in materials of high technological impact, their processing and their transfer to the productive sectors at local, national and European scales (the true value of materials is in their use), the training of new professionals, and the dissemination of the scientific knowledge.

Free-radical polymerizations of and in deep eutectic solvents: Green synthesis of functional materials

Josué D.Mota-Morales, Regina J., Sánchez-Leija, Arturo Carranza, John A.Pojman, Francisco del Monte, Gabriel Luna-Bárcenas

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