The present invention concerns a method for producing a hydrogel comprising the following steps in succession:

Method for the production of hydrogel comprising chitosan and negatively charged polyelectrolytes, and cellular, porous material resulting from said hydrogel

A method for preparing a biomaterial containing at least one bioactive molecule from a base biomaterial, comprising the following successive operations carried out on the base biomaterial:

Biomaterials carrying cyclodextrins having improved absorption properties and used for the progressive and delayed release of therapeutic molecules

The present invention concerns a process for treating a fiber or a fiber-based material such as a yarn, a woven, knitted or nonwoven textile material, paper, or leather, to improve its adsorption properties, wherein the following successive operations are carried out on said fiber or said material: The present invention also concerns fibers or fiber-based materials with improved cation exchange properties and improved hydrophilic characteristics.

Fiber with improved complexation qualities and cation-exchange properties

The present invention concerns a process for preparing copolymers of cyclodextrin(s) and/or cyclodextrin derivative(s), characterized by the following operations: (a) preparing a solid state mixture of cyclodextrin(s) and/or cyclodextrin derivative(s) and/or inclusion complex(es) of cyclodextrin(s) and/or cyclodextrin derivative(s) and a poly(carboxylic) acid and/or a poly(carboxylic) acid anhydride or a mixture of poly(carboxylic) acid(s) and/or poly(carboxylic) acid anhydride(s), and optionally, a catalyst; and (b) heating the solid mixture to a temperature in the range 100&deg; C. to 200&deg; C. for a period in the range 1 min to 60 min, preferably 30 min or substantially 30 min. The present invention also concerns soluble and insoluble compounds of cyclodextrin(s) and/or cyclodextrin derivative(s) or their inclusion complexes with at least one poly(carboxylic) acid.

Cyclodextrin polymers and/or cyclodextrin derivatives with complexing properties and ion-exchange properties and method for the production thereof
