Abstract
La presente invención 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 componente de monómero continua en la que dicha fase de componente de monómero contínua comprende como mínimo un monómero que tiene al menos una unidad de perfluoropoliéter y donde dicho porógeno es un poli(alquilen)glicol opcionalmente sustituído, 2) polimerizar a continuación la fase de monómero continua; y 3) eliminar el porógeno del polímero poroso.The present invention relates to a process for the production of a porous polymer comprising the steps of: 1) Dispersing a porogen in a continuous monomer component phase in which said continuous monomer component phase comprises at least one monomer that it has at least one perfluoropolyether unit and where said porogen is an optionally substituted poly (alkylene) glycol, 2) then polymerizing the continuous monomer phase; and 3) removing the porogen from the porous polymer.
