Verfahren zur Aufbereitung von mit biologischen Material verunreinigten Polymeren durch Auflösen in wässrig alkalischem Medium, Abtennen der ungelösten Bestandteile, Entfernen der biologischen Verunreinigungen durch bakterielle Zersetzung und Ausfällen der Polymere durch Ansäuern. A process for the work-up of polymers which have been contaminated by biological material, by dissolving the polymers in an aqueous alkaline medium, separating off the insoluble constituents, removing the biological impurities by bacterial decomposition and precipitating the polymers by acidification.
