Abstract

METODO PARA POLIMERIZAR CONTINUAMENTE EN MASA POLIMEZCLAS QUE TIENEN UNA FASE DE CAUCHO DIENICO DISPERSADA EN FORMA DE PARTICULAS CON UNA DISTRIBUCION POR TAMAÑOS BIMODAL. CONSTA DE LAS SIGUIENTES ETAPAS; PRIMERA, CARGAR CONTINUA Y SIMULTANEAMENTE UNA PRIMERA Y UNA SEGUNDA SOLUCIONES DE MONOMERO-CAUCHO EN UNA PRIMERA ZONA DE REACCION; SEGUNDA, POLIMERIZAR CONTINUAMENTE LA PRIMERA Y SEGUNDA SOLUCIONES BAJO CONDICIONES DE ESTADO ESTABLE HASTA ALCANZAR UNA TRANSFORMACION DE MONOMERO EN POLIMERO DEL 15 AL 50 POR 100, MIENTRAS SE DISPERSAN CONTINUAMENTE EN LA SOLUCION PARCIALMENTE POLIMERIZADA PARTICULAS PROCEDENTES DE LA PRIMERA SOLUCION DE UN TAMAÑO APROXIMADO DE 0,5 A 1 MICRAS Y PARTICULAS PROCEDENTES DE LA SEGUNDA SOLUCION DE UN TAMAÑO APROXIMADO DE 2 A 10 MICRAS; TERCERA, EXTRAER CONTINUAMENTE LA SOLUCION PARCIALMENTE POLIMERIZADA DE LA PRIMERA ZONA DE REACCION Y PASARLA A LA SEGUNDA ZONA DE REACCION DE FLUJO DIRECTO, DONDE SE LA CONTINUA POLIMERIZANDO ADICIONALMENTE HASTA ALCANZAR UNA CONVERSION DE LOS CITADOS MONOMEROS EN POLIMEROS DEL 20 AL 95 POR 100; Y POR ULTIMO, EXTRAER CONTINUAMENTE UN EFLUENTE DE LA SEGUNDA ZONA DE REACCION Y SEPARAR DE DICHO EFLUENTE LA POLIMEZCLA FORMADA. DE USO EN LA PREPARACION DE PLASTICOS MOLDEABLES O EXTRUSIONABLES DE ELEVADA RIGIDEZ. A
