CROSSLINKING OF POLYSACCHARIDE(S), PREPARATION OF HYDROGEL(S), POLYSACCHARIDE(S) AND HYDROGELS(S) OBTAINED AND THEIR USES

摘要

The invention relates to a process for the crosslinking of polysaccharides . The process of the invention is a process for the crosslinking of at least o ne polymer selected from polysaccharides and their derivatives, under the actio n of at least one polyfunctional crosslinking agent, characterized in that said polyfunctional crosslinking agent is reacted with said polymer, in the solid state, during hydration. The invention is applied to the manufacture of hydrogels a nd gels that can be used, in particular, in plastic or cosmetic surgery.
