POLYMER HAVING QUATERNARY AMINO GROUPS

摘要

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 < IMG > where R1, R2 and R3, 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.
