Abstract

Se presenta un proceso y un dispositivo correspondientemente apropiado para preparar homopolímeros o bien copolímeros de al menos uno de los monomeros polímerizables del grupo que consiste de estíreno, butadieno, cloruro de vinilo , acetato de vinilo, cloruro de vinilideno, (met)acrilato de alquilo, ácido (met)acrilico, (met)acrilontrilo y (met)acrilamída, en donde la reaccion de lleva a cabo a una temperatura de al menos 40 degree C en precencia de un auxiliar de dispersion y de un iniciador de polímerizacion de radicales libres de tal manera que al menos el 85% en peso del polímero se forma de estos monomeros. En el proceso de etapas multiples el procedimiento es tal que: a) en una etapa se agrega agua como solvente que es inerte en la reaccion, y auxiliares de dispersion, semillas y una primera porcion de monomero(s) se agregan, si se desea, b) en una etapa, se agrega un iniciador, y c) en una tercera etapa se agrega el resto del o de los monomero(s) directamente o bien en forma de emulsion y en presencia de agua adicional y, si se desea, auxiliar de dispersion adicional o bien otros auxiliares, es también posible llevar a cabo cualquiera de dos atapas en forma de una etapa unica. La mezcla de la reaccion que se encuentra en forma de emulsion, es desplazada en todas las etapas o bien en ciertas etapas a través de un circuito externo que lleva a partir del recipiente de reaccion y de regreso hacia dicho recipiente de reaccion y que comprende al menos una bomba de bajo esfuerzo cortante y al menos un intercambiador de calor que tiene un perfil de flujo esencialmente laminar. Los productos preparados mediante este proceso, que incluye un intercambiador de calor que tiene un perfil de flujo esencialmente laminar. Los productos preparados mediante este proceso incluye unos períodos cortos de preparacion, tienen buenas propiedades de desempeño (para uniones adhesivas, por ejemplo).
