Abstract
The present invention relates to polymerizable derivatives of carbohydrates comprising a carbohydrate radical and more than one radically polymerizable hydrocarbon group which is linked optionally via a spacer to the carbohydrate radical, to homopolymers, copolymers, block copolymers, graft copolymers and polymeric networks thereof, to capsules, fibers, films and coatings having water-binding and biocompatible properties, and to molded articles, for example contact lenses or biomedicinal articles, comprising the mentioned polymers, as well as to processes for the preparation of the mentioned polymers and articles.
