Beschreibung
Zusammenfassung:	V-17364/+/T1T7 Hydrogels based on fluorine-containing saccharide monomers The invention relates to a hydrogel which is a copolymer of a polymerizable monomer mixture which contains a) 2-85 mol-% of a hydrophobic vinyl monomer with at least three fluorine atoms,b) 2-80 mol-% of a hydrophobic polyhydroxy vinyl 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 crosslinker, in which hydrogel the hydroxyl groups of the segments formed by the monomers b) are in protected or in free form. These hydrogels can be used, for example, as contact lenses, intraocular lenses or in other areas of application where biologically tolerated materials are required.
