V-17531/+/TIT 8 Hydrogels based on sugar alcohol monomers of the disclosure The invention relates to a hydrogel which is a copolymer of a polymerizable monomer mixture which contains a) 5-95 mole % of a hydrophobic polyhydroxyvinyl monomer whose hydroxyl groups are in protected form, b) 5-95 mole % of a hydrophilic vinyl monomer, c) 0-40 mole % of a hydrophobic vinyl monomer containing a maximum of two fluorine atoms, and d) 0-5 mole %, relative to the total amount of monomers a)-c), of a crosslinking agent, in which hydrogel the hydroxyl groups of the segments formed by the monomers a) are in protected or free form, and the proportion of the hydrophobic vinyl monomer c), if it is not zero, is at least 25 mole %. These hydrogels can be used, for example, as contact lenses, intraocular lenses or in other areas of application in which biocompatible materials are necessary. |
