ALDEHYDE CATIONIC DERIVATIVES OF GALACTOSE CONTAINING POLYSACCHARIDES USED AS PAPER STRENGTH ADDITIVES

摘要

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 C6 position, of the galactose unit, and the cationic derivatives thereof have unexpected and significantly improved properties when used as paper strength additives.
