ABSTRACT:
The invention relates to a new polymer containing quarternary amino group based on dextran or cross-linked dextran. The quarternary amino groups are of the formula ##STR1## where R.sub.1, R.sub.2 and R.sub.3, which may be identical or different, are lower alkyl groups of 1-5 carbon atoms or lower hydroxyalkyl groups of 2-5 carbon atoms and 1-2 hydroxy groups. At most one atom other than carbon and hydrogen is bound to the same carbon atom in the hydroxy alkyl group.
