Abstract

LA PRESENTE INVENTION CONCERNE UN AMIDON HYDROXYETHYLE RETICULE. L'AMIDON HYDROXYETHYLE EST AMENE A RETICULER NOTAMMENT A L'AIDE DE GLYCERINE OU D'AUTRES RESTES BIFONCTIONNELS. IL CONTIENT AU MOINS 90 D'AMYLOPECTINE ET PRESENTE UN DEGRE DE SUBSTITUTION D'EHER AU MOINS EGAL A 0,90 GROUPES D'HYDROXYETHYLE PAR MOLECULE D'AMIDON. POUR OBTENIR LA RETICULATION, ON PEUT UTILISER DE L'EPYCHLORHYDRINE NOTAMMENT. LA FABRICATION DE CET AMIDON HYDROXYETHYLE RETICULE DOIT ETRE EXECUTEE SOUS ATMOSPHERE STERILE. L'INVENTION EST UTILISEE EN MEDECINE COMME SUBSTANCE ABSORBANTE DES SECRETIONS DE PLAIES OU D'ULCERES.THE PRESENT INVENTION CONCERNS A CROSS-LINKED HYDROXYETHYL STARCH. HYDROXYETHYL STARCH IS ENCOURAGED TO CROSS-LINK IN PARTICULAR WITH GLYCERINE OR OTHER BIFUNCTIONAL REMAINS. IT CONTAINS AT LEAST 90 AMYLOPECTIN AND SHOWS A DEGREE OF EHER SUBSTITUTION AT LEAST EQUAL TO 0.90 HYDROXYETHYL GROUPS PER STARCH MOLECULE. TO OBTAIN CROSS-LINKAGE, EPYCHLORHYDRIN MAY BE USED IN PARTICULAR. THE MANUFACTURE OF THIS CROSS-LINKED HYDROXYETHYL STARCH MUST BE CARRIED OUT IN A STERILE ATMOSPHERE. THE INVENTION IS USED IN MEDICINE AS AN ABSORBENT SUBSTANCE OF SECRETIONS FROM WOUNDS OR ULCERS.
