Abstract

Die Erfindung bezieht sich auf das Gebiet der Chemie und betrifft eine Membran, wie sie beispielsweise in Ultrafiltrationsprozessen zum Einsatz kommen kann. Die Aufgabe der vorliegenden Erfindung besteht in der weiteren Verbesserung der Biokompatibilität unter gleichzeitiger Bewahrung ihrer positiven Eigenschaften. Gelöst wird die Aufgabe durch eine Membran, bestehend aus Cellulose und darin homogen verteilt bis zu 2,5 Ma.-% Vinylpyrrolidon-Vinylimidazol-Copolymere (VP-VI) und/oder mit bis zu 2,5 Ma.-% an der Oberfläche der Cellulose gebundenen biocompatiblen, hydrophilen Polymeren mit einer Molaren Masse von ≥ 3000 g/mol. Die Aufgabe wird weiterhin gelöst durch ein Verfahren, bei dem aus Vinylpyrrolidonen und Vinylimidazolen ein Copolymer (VP-VI) hergestellt und nachfolgend bis zu 2,5 Ma.-% des Copolymers und/oder bis zu 2,5 Ma.-% biocompatible, hydrophile Polymere mit einer Molaren Masse von ≥ 3000 g/mol homogen mit einer Cellulosexanthogenatlösung vermischt werden und daraus eine Membran hergestellt wird.
