Title
(EN) PROCESS FOR THE MANUFACTURE OF CELLULOSE SULFATE WITH IMPROVED CHARACTERISTICS
(FR) PROCEDE DE FABRICATION DE SULFATE DE CELLULOSE AUX PROPRIETES AMELIOREES
Abstract
(EN)
The invention refers to a method for the production of cellulose sulfate which is completely water-soluble and has an adjustable solution viscosity in aqueous solution, which qualifies the produced sodium cellulose sulfate (SCS) as auxiliary material with ideal biological compatibility for biological and medical applications, in particular it is suitable for the encapsulation and immobilization of biological objects, e.g. tissue, cells, microorganisms, enzymes or viruses in microcapsule.
(FR)
L’invention concerne une méthode de fabrication de sulfate de cellulose complètement hydrosoluble et ayant une viscosité ajustable en solution aqueuse, le sulfate de cellulose sodique (SCS) ainsi obtenu pouvant être qualifié de matériau auxiliaire avec une compatibilité biologique idéale pour les applications biologiques et médicales, et en particulier pour l’encapsulation et l’immobilisation d’objets biologiques, par ex. des tissus, des cellules, des microorganismes, des enzymes ou des virus en microcapsule.
