Abstract
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.
Claims2
A method for preparing a polymer hydrogel, comprising the steps of:
- (a) providing an aqueous solution comprising a hydrophilic polymer and a polycarboxylic acid or an anhydride thereof, wherein said polycarboxylic acid is a C4-C12-dicarboxylic acid, a tricarboxylic acid or a tetracarboxylic acid;
- and
- (b) maintaining the solution of step (a) under conditions suitable for cross-linking of the hydrophilic polymer by the polycarboxylic acid;
- thereby forming a polymer hydrogel.
