Résumé:
The polymers are less expensive and much usually in treatment of water. And from of these polymers: the cellulose which takes important place and his chemical structure.
This polysaccharide is linear withdraw in his surface which contain a multitude functional
grouping able to function. And we propose doing something functionalized with retractors adequate for obtaining materials cellulosic’s bi voice tridimensional by reticulation of polymer of depart : the cellulose.
