HIDROGELES A BASE DE MONOMEROS QUE CONTIENEN FLUOR Y MONOMEROS DE SACARIDO

EL INVENTO SE REFIERE A UN HIDROGEL, EL CUAL ES UN COPOLIMERO DE UNA MEZCLA POLIMERIZABLE DE MONOMERO, QUE CONTIENE: A) 2-85 MOLES % DE UN MONOMERO VINILICO HIDROFOBO, CON AL MENOS TRES ATOMOS DE FLUOR, B) 2-80 MOLES % DE UN MONOMERO DE POLI-HIDROXIVINILO HIDROFOBO, CUYOS GRUPOS HIDROXI SE ENCUENTRAN PROTEGIDOS, C) 2-70 MOLES % DE UN MONOMERO VINILICO HIDROFILO Y D) 0-5 MOLES % DE UN HUMECTANTE REFERIDO A LA CANTIDAD TOTAL DE LOS MONOMEROS A) Y C), EN CUYO HIDROGEL LOS GRUPOS HIDROXI DE LOS SEGMENTOS FORMADOS POR LOS MONOMEROS B) SE ENCUENTRAN EN FORMA PROTEGIDA O EN LIBERTAD The invention relates to a hydrogel which is a copolymer made from a polymerisable monomer mixture which contains a) 2-85 mol-% of a hydrophobic vinyl monomer having at least three fluorine atoms, b) 2-80 mol-% of a hydrophobic polyhydroxyvinyl monomer whose hydroxyl groups are in protected form, c) 2-70 mol-% of a hydrophilic vinyl monomer and d) based on the total amount of monomers a)-c), 0-5 mol-% of a crosslinking agent, the hydroxyl groups of the segments formed by monomer b) in said hydrogel being in protected or free form. These hydrogels can be used, for example, as contact lenses, intraocular lenses or in other areas of application in which biocompatible materials are required.
