Abstract

Abstract Translated from German Die Erfindung betrifft modifizierte Polymerisate auf Basis von Polyvinylencarbonat und/oder Polyhydroxymethylen, wobei die Modifizierung durch bestimmte in das Polymerisat eingebaute alkoxylierte Verbindungen erfolgt. Diese Polymerisate, bei deren Herstellung erfindungsgemäß bestimmte Dispersionsstabilisatoren eingesetzt werden, eignen sich u.a. als Trägermaterialien für biologisch aktive Substanzen oder für die Affinitätschromatographie. The invention relates to modified polymers based on polyvinylene carbonate and / or polyhydroxymethylene, the modification being carried out by means of certain alkoxylated compounds incorporated into the polymer. These polymers, in the production of which certain dispersion stabilizers are used according to the invention, are suitable, inter alia. as carrier materials for biologically active substances or for affinity chromatography.
