Abstract

Procedimiento continuo para la síntesis de un polímero con separación de una sustancia gaseosa en un dispositivo comprendiendo - una cámara de reacción (1), que comprende una sección superior (11) esencialmente cilíndrica circular, limitada por dos superficies circulares (111, 112) y una superficie lateral (113) y que presenta un eje longitudinal del cilindro, así como una sección inferior (12), estando la sección superior (11) y la sección inferior (12) unidas a través de la primera superficie circular (111), - un orificio de entrada (2), que se dispone de tal forma en la superficie lateral (113), que se posibilite una entrada tangencial de un líquido a través del orificio de entrada (2) a lo largo de la superficie lateral (113) en la sección superior (11), - un primer orificio de salida (3), dispuesto en una pared de la sección inferior (12), - un segundo orificio de salida (4), dispuesto en la segunda superficie circular (112) o en la superficie lateral (113) entre el orificio de entrada (2) y la segunda superficie circular (112), y - al menos un primer dispositivo de retirada (51), que se dispone de manera desplazable por lo menos entre la segunda superficie circular (112) y el orificio de entrada (2) a lo largo del eje longitudinal del cilindro y está en contacto con la superficie lateral (113), con los siguientes pasos procedimentales: a) introducción de una masa fundida de prepolímero (7) en una primera sección cilíndrica circular (11) de una cámara de reacción (1) a través de un orificio de entrada (2) tangencialmente a una superficie lateral (113) de la primera sección (11), b) polimerización de la masa fundida de prepolímero (7) para dar una masa fundida de polímero (8), c) extracción de la masa fundida de polímero (8) de la cámara de reacción (1) a través de un primer orificio de salida (3) de la cámara de reacción (1), y d) extracción de una sustancia gaseosa (9) de la cámara de reacción (1) a través de un segundo orificio de salida (4) de la cámara de reacción (1) por encima del orificio de entrada (2), caracterizado porque los depósitos en por lo menos una pared interna de la sección superior (11) de la cámara de reacción (1) por encima del orificio de entrada (2) los elimina al menos el primer dispositivo de retirada (51).
