    Abstract: Procedimiento para la preparación continua de un polímero mediante polimerización en solución o en masa por radicales, que comprende las siguientes etapas: (a) facilitación de al menos dos corrientes líquidas, comprendiendo las al menos dos corrientes líquidas en cada caso uno o varios de los siguientes componentes: un monómero que se puede polimerizar por radicales, un regulador seleccionado entre disolventes que actúan como regulador y reguladores distintos de los mismos y un iniciador, a condición de que la corriente que contiene el iniciador no contenga también el regulador, (b) mezcla de las al menos dos corrientes líquidas con obtención de una mezcla de reacción, realizándose la mezcla de las corrientes líquidas al menos 20 ºC por debajo de la temperatura de reacción de la siguiente polimerización y empleándose al menos una mezcladora con microestructuras y (c) polimerización por radicales de la mezcla de reacción obtenida en la etapa (b) en al menos una zona de reacción microestructurada con una dimensión característica de como máximo 4 mm.

    Abstract: Method for continuous polymerization of cationically polymerizable monomers, comprises: (a) providing at least two liquid streams comprising at least one of the monomer, at least one boron trifluoride complex and/or optionally at least one solvent, provided that the stream comprising the boron trifluoride complex does not contain the monomer; (b) mixing the two liquid streams to obtain a reaction mixture, where the mixing is successive or simultaneous and is carried out in a mixer having microstructures; and (c) polymerizing the reaction mixture in at least one reaction zone. Method for continuous polymerization of cationically polymerizable monomers, comprises: (a) providing at least two liquid streams comprising at least one cationically polymerizable monomer, at least one boron trifluoride complex having at least one cocatalyst and/or optionally at least one solvent, provided that the stream comprising the boron trifluoride complex does not contain the monomer; (b) mixing the two liquid streams to obtain a reaction mixture, where the mixing is successive or simultaneous and is carried out in a mixer having microstructures; and (c) polymerizing the reaction mixture in at least one reaction zone. Independent claims are included for a device, for carrying out the above process, comprising at least two or three storage containers (1,4) for liquid starting materials; two feeders, each one for feeding the liquid stream from at least two storage containers; one or more sequentially-connected mixers (3) to which the liquid streams are fed and in which the obtained reaction mixture is mixed, where at least the last mixer in the direction of flow is equipped with microstructures before entering into the reaction zone(s); at least one reaction zone, which is microstructured; and a discharge container (11) that is optionally provided with one or more devices for adding and/or mixing.
