Polymer hydrogels and methods of preparation thereof

摘要

The invention relates to a method for the preparation of a polymer hydrogel, comprising cross linking a precursor comprising a hydrophilic polymer optionally in combination with a second hydrophilic polymer, using a polycarboxylic acid as the cross-linking agent. The invention further concerns the polymer hydrogel obtainable by the method of the invention and the use thereof in a number of different applications.
