ABSTRACT:
Aldehyde cationic derivatives of galactose containing polysaccharides which are obtained by oxidizing galactose containing polysaccharides with the enzyme galactose oxidase. The enzyme oxidized products have an aldehyde function at a specific position of the polysaccharide, i.e., the C.sub.6 position, of the galactose unit, and the cationic derivatives thereof have unexpected and significantly improved properties when used as paper strength additives.
