    Description / Table of Contents: Cellulose acetate as well as polysulphon are well established polymers for the production of ultrafiltration membranes. Contrary to the former polysulphon is not suitable for enzyme immobilization. These difficulties can be eliminated by introduction of distinct substituents, but by this process the film forming tendency is lost. By mixing the original polymer with the substituted material a casting solution can be obtained to producing heterogeneous membranes. The enzymes dextranase and urease were fixed and the activated membranes were tested using dextrane and urea as substrates.
    Notes: Im Gegensatz zu Celluloseacetat ist Polysulfon, ebenfalls ein Polymeres zur Herstellung von Ultrafiltrationsmembranen, für Kupplungsreaktionen mit Enzymennicht geeignet. Die Einführung von entsprechenden Substituenten ist möglich, dabei gehen aber die Filmbildungstendenzen verloren. Im Gemisch mit originalem Polymeren wurden Gießlösungen erhalten, die heterogene Membranen ergeben, an die Dextranase und Urease fixiert wurden. Die Wirkungsweise der aktiven Membranen wurde mit Dextran und Harnstoff untersucht.
