Abstract
En vannoppløselig, tverrblndbar forpolymer som l polymerkjeden inneholder enheter som er avledet fra følgende roonoroerbyggestener: et vinyllaktam (a), vinylalkohol (b), eventuelt en laverealkankarboksyl- syrevinylester (c), en vlnylisk tverrblnder (d) og eventuelt en vinylisk fotolnltlator (e). Videre beskrives en fremgangsmåte for fremstilling av disse forpolymerer, tverrbundne, vannuoppløselige, polymere nettverk inneholdende forpolymeren, hydrogeler og formlegemer som er fremstilt fra de tverrbundne, vannuoppløselige, polymere nettverk og særlig kontakt- linser, samt fremgangsmåter for fremstilling av hydrogeler og ferdige kontaktlinser under anvendelse av de nevnte tverrbindbare, vannoppløselige forpolymerer.A water-soluble, cross-linkable prepolymer containing in the polymer chain contains units derived from the following roonoro building blocks: a vinyl lactam (a), vinyl alcohol (b), optionally a lower-alkane carboxylic acid vinyl ester (c), a vinyl crosslinker (d) and optionally a vinyl alcohol (d) and optionally ). Further disclosed is a process for preparing these prepolymers, cross-linked, water-insoluble polymeric networks containing the prepolymer, hydrogels and moldings made from the cross-linked, water-insoluble polymeric networks and particularly contact lenses, as well as methods for preparing hydrogels and ready-to-use contact lenses. of said crosslinkable, water-soluble prepolymers.
