    Description / Table of Contents: On the basis of poly(vinyl alcohol) various reactive carriers for the immobilization of enzymes were synthesized. Starting as well from hydrolyzed beads of crosslinked poly(vinylacetate), as from tubes of poly(vinyl acetate-co-ethylene) which have been coated with poly(vinyl alcohol) resp. from poly(vinyl alcohol) containing synthetic pulp reactive carriers were synthesized by reaction with 2-(3-aminophenyl)-1,3-dioxolane followed by diazotization. Furthermore reactive isothiocyanato groups as well as mixed polymeric disulfides with 2-thiopyridine groups were introduced into gels of poly(vinyl alcohol) which were crosslinked with terephthalaldehyde. The immobilization of enzymes was carried out with papain, trypsin, glucose oxidase, and catalase. The properties of the immobilized enzymes were investigated.
    Notes: Verschiedene reaktive Träger für die Immobilisierung von Enzymen wurden auf der Basis von Polyvinylalkohol synthetisiert. Ausgehend von einem Hydrolysat eines Perlpolymeren aus vernetztem Polyvinylacetat sowie von mit Polyvinylalkohol beschicteten Schl¨chen aus Poly(vinylacetat-co-ethylen) bzw. von Polyvinylalkohol enthaltendem Synthesepulp wurden reaktive Träger durch Umsetzung mit 2-(3-Aminophenyl)-1,3-dioxolan und nachfolgender Diazotierung hergestellt. Weiterhin wurden in Gele eines mit Terephthalaldehyd vernetzten Polyvinylalkohols reaktive Isothiocyanatgruppen sowie 2-Thiopyridingruppen enthaltende gemischte polymere Disulfide eingeführt. Die Enzyme Papain, Trypsin, Glucose-Oxydase und Katalase wurden immobilisiert und die Eigenschaften der immobilisierten Enzympräparate untersucht.
