Abstract
Se refiere a un procedimiento para la producción de un polímero poroso que comprende los pasos de: i)formar una mezcla que comprenda un componentepolimerizable y un solvente orgánico donde el componente polimerizable comprende como mínimou n macromonómero que tiene al menos una unidadde perfluoropoliéter; ii)polimerizar dicha mezcla en la que inmediatamente luego de la polimerización de dicha mezcla como mínimo una proporciónsustancial de dicho solvente orgánico se encuentra enfo rma de fase discreta y donde dicha fase de solvente orgánico discreta forma una red interpenetranteen toda la mezcla o se dispersa por toda la mezcla; y iii)quitar la fase de solvente orgánico discreta. Asimismo se refiere al polímeroporoso asípreparado y a la utilización de dicho polímero en forma de película o lámina, como una membrana o filtro o como dispositivo oftálmico.
