| description | Billes à base de chitosane, préparation, compositions et applications L'invention concerne des billes et une composition comprenant une phase aqueuse comprenant une pluralité de billes, les billes comprenant ou consistant en une matrice d'hydrogel comprenant au moins un carboxyalkyl chitosane présentant des unités glucosamine, des unités N-acétyl-glucosamine et des unités glucosamine substituées par un groupe carboxyalkyl, le carboxyalkyl chitosane étant réticulé par liaisons covalentes entre les chaînes de carboxyalkyl chitosane et/ou co-réticulé par liaisons covalentes avec un ou plusieurs autres polymères. L'invention concerne également leurs procédés de préparation et leurs applications. Figure pour l'abrégé : NEANT
The invention relates to beads and a composition comprising an aqueous phase comprising a plurality of beads, the beads comprising or consisting in a hydrogel matrix comprising at least one carboxyalkyl chitosan having glucosamine units, N-acetyl-glucosamine units and glucosamine units substituted with a carboxyalkyl group, the carboxyalkyl chitosan being crosslinked by covalent bonds between the carboxyalkyl chitosan chains and/or co-crosslinked by covalent bonds with one or more other polymers.The invention also relates to processes for their preparation and applications thereof. |
