Abstract (en)
[origin: WO2004092222A2] The invention relates to a method for cross-linking at least one polymer, selected from the polysaccharides and the derivatives thereof, application thereof in an aqueous solvent, by the action of an effective and non-excessive quantity of at least one cross-linking agent, characterised in being applied to a mixture including at least one polymer of low molecular weight and at least one polymer of high molecular weight, a method for preparation of an injectable monophase hydrogel with at least one cross-linked polymer selected from polysaccharides and the derivatives thereof and the cross-linked polymers and injectable monophase hydrogels which may be obtained respectively by the methods above.
