Abstract

Se refiere a un procedimiento para la producción de un polímero poroso que comprende los pasos de: 1)dispersar un porógeno en una fase de componentede monómero continua en la que dicha fase de componente de monómero continua comprende comomínimo un monómero que tiene al menos una unidad deperfluoropoliéter y donde dicho porógeno es un poli(alquilen)glicol opcionalmente sustituido; 2)polimerizar a continuación la fase de monómerocontinua; y 3) eliminar el porógeno delpolímero po roso. Asimismo también comprende al polímero poroso preparado con dicho procedimiento y asu utilización en forma de película o lámina, membrana o filtro y como dispositivo oftálmico.
