    Description / Table of Contents: Polymer bound microbiocides are prepared by 4-dimethylaminopyridine catalyzed acylation of cellulose and cellulose dibenzylether with the thio acid chloride obtained from 3-methyl-pyrazole and thiophosgene. The hydrolytic release of the bioactive compound is controlled primarily by the hydrophilicity of the polymer support and the state of swelling and dissolution of the polymer-biocide-combination and its change during hydrolysis.
    Notes: Polymergebundene Mikrobiocide werden durch Acylierung von Cellulose und Cellulosedibenzylether mit dem aus 3-Methyl-pyrazol und Thiophosgen erhältlichen Thiocarbonsäurechlorid unter Katalyse mit 4-Dimethylamino-pyridin hergestellt. Die hydrolytische Wirkstoffreisetzung wird primär über die Hydrophilie der Trägerpolymere sowie den Quellungs- bzw. Lösungszustand der Polymer-Wirkstoff-Kombination und seine Änderung während der Hydrolyse gesteurt.
