Abstract
Un proceso para polimerizar monómeros de vinilo en un medio acuoso espesado, que comprende los pasos de: (a) cargar agua y al menos un dispersante capaz de espesar el agua en un recipiente de polimerización equipado con medios de agitación y de refrigeración; (b) agitar el agua y el dispersante; (c) reducir o detener la agitación para que se consiga un flujo no turbulento; (d) cargar al menos un monómero de vinilo al recipiente de polimerización para que se formen dos capas de líquido en el recipiente de polimerización, una capa acuosa espesada inferior y una capa de monómero de vinilo superior; (e) cargar en la capa superior de monómero de vinilo una solución que comprende al menos un catalizador generador de radicales libres solubles en aceite, al menos un disolvente y opcionalmente al menos un agente secundario activo en la superficie; (f) dejar que el catalizador se difunda a través de la capa superior de monómero de vinilo; (g) incrementar la agitación para que se emulsione todo el medio de polimerización; (h) conducir la polimerización del monómero de vinilo para formar partículas porosas de resina; (i) retirar la resina polimerizada del recipiente de reacción, caracterizado porque el proceso comprende cargar dicho catalizador generador de radicales libres como solución que comprende opcionalmente agente(s) activos(s) en la superficie seleccionado(s) del grupo que consta de agentes no-iónicos que contienen poliéter, ésteres de sorbitan, ésteres de glicerol, ésteres de poliglicerol y alcoholes polivinílicos parcialmente hidrolizados, y dicho catalizador generador de radicales libres, en la que el disolvente para la solución de catalizador es un disolvente mutuo para todos los materiales contenidos en la solución y no se produce inestabilidad coloidal.
