Abstract

The invention relates to poly(oligo(ethylene glycol) methacrylate) microgels, to the process for preparing same and the uses thereof in various fields of application such as optics, electronics, pharmacy and cosmetics.These microgels have the advantage of being monodisperse, pH-responsive and temperature-responsive. They can carry magnetic nanoparticles or biologically active molecules. These microgels may also form transparent films, which have novel optical and electromechanical properties.
