Abstract

Se refiere a polímeros porosos que comprenden una unidad de perfluoropoliéter, un procedimiento para producir dichos polímeros porosos,en particular a un procedimiento para polimerizar o copolimerizar monómeros que incorporan perfluoropoliéteres para formar polímeros porosos, aartículos fabricados de, o incluyendo, polímeros porosos que comprenden una unidad de perfluoropoliéter, tales como membranas o dispositivos oftálmicos,y a la utilización de polímeros porosos que comprenden unidades de perfluoropoliéter como artículos, tales como membranas o dispositivosoftálmicos. Las unidades de perfluoropoliéter son preferentemente de fórmula PFPE: -OCH2CF2O(CF2CF2O)x(CF2O)yCF2CH2O- (PFPE), donde lasunidadesCF2CF2O y CF2O pueden estar distribuidas en forma aleatoria o en forma de bloques a lo largo de la cadena y donde x e y puden ser iguales o diferentesde forma que el peso molecular del poliéter perfluorado esté comprendido entre 242 yy y 4.000. Los polímeros porosos comprenden una o más unidades deperfluoropoliéter con mayor contenido de agua al estar completamente expandidos en agua que el del mismo polímero polimerizado bajo condicionesconvencionales, y son adecuadospara la aplicación, por ejemplo, como lentes de contacto blandas.It relates to porous polymers comprising a perfluoropolyether unit, a process for producing such porous polymers, in particular to a process for polymerizing or copolymerizing monomers incorporating perfluoropolyethers to form porous polymers, to articles made of, or including, porous polymers comprising a perfluoropolyether units, such as ophthalmic membranes or devices, and to the use of porous polymers comprising perfluoropolyether units as articles, such as ophthalmic membranes or devices. The perfluoropolyether units are preferably of the PFPE formula: -OCH2CF2O (CF2CF2O) x (CF2O) yCF2CH2O- (PFPE), where the CF2CF2O and CF2O units can be distributed randomly or in the form of blocks along the chain and where x and y can be be the same or different so that the molecular weight of the perfluorinated polyether is between 242 yy and 4,000. Porous polymers comprise one or more perfluoropolyether units with higher water content when fully expanded in water than that of the same polymerized polymer under conventional conditions, and are suitable for application, for example, as soft contact lenses.
