Abstract: The hydrogels consist essentially of the polyurethane of polyoxyethylene. The crosslinking is carried out by a reaction of a polyfunctional isocyanate with the polyoxyethylene in solution in a non-aqueous solvent. Transparent hydrogels are obtained, having a high swelling ratio in the presence of water and good mechanical properties.
