The invention relates to a method for continuously and dynamically mixing at least two fluids. Said method comprises the following steps: a) the rotor (1) of a micromixer is rotatably driven, said micromixer comprising a rotor (1) which is provided with a shaft (2) encompassing blades (3) that are arranged in groups (3a - 3g), a stator (4) which is provided with at least one inlet (5) for a first fluid, at least one inlet (6) for a second fluid, and an outlet (7); b) the fluids are fed into the micromixer; and c) a micromixture of the fluids is collected at the outlet (7) of the micromixer. The inventive method is particularly suitable for rapid and/or complex kinetic chemical reactions such as anionic polymerization. The invention also relates to a micromixer for carrying out said method.
L'invention concerne un procédé pour mélanger en continu et dynamiquement au moins deux fluides. Ce procédé comprend les étapes suivantes : a) on entraîne en rotation le rotor (1) d'un micromélangeur comprenant : - un rotor (1) comprenant un arbre (2) muni de pales (3) réparties par groupes (3a - 3g), - un stator (4) comprenant au moins une entrée (5) pour un premier fluide, au moins une entrée (6) pour un second fluide et une sortie (7); b) on introduit les fluides dans le micromélangeur; et c) on récupère à la sortie (7) du micromélangeur un micromélange des fluides. Il est particulièrement adapté aux réactions chimiques de cinétique rapide et/ou complexe, telles que les polymérisations anioniques. L'invention concerne également un micromélangeur pouvant mettre en .oelig.uvre ce procédé.
