| English abstract | A model based on kinetic, thermodynamic and physicochemical concepts, is presented and an integrodifferential approach to find the fundamental events, is used for microemulsion polymerization (MEP), the procedure was applied to experimental conversion data of hexyl methacrylate (C6MA) and styrene (STY) in MEP. It was found that: (i): nucleation rate is not linear with time, opposed to previous reports, (ii): coagulation rate is negligible , (iii): micelles provide monomer to reacting particles, (iv) a vitreous effect , even in polymers with a Tg lower than the reaction temperature, was found, (v): radical entry to particles is negligible conforming a previous reports, (vi) the decreasing reaction rate interval, besides monomer depletion, is caused by a decrease in active reaction sites, and (vii) a three-parameter phenomenological model is presented capable of describing the studied systems |
