ABSTRACT:
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.
