    Abstract: A process for preparing novel cationic flocculating agents and paper wet-end additives is disclosed wherein water-dispersible polysaccharides, colloidally dispersed in an aqueous alkaline medium are reacted with polyfunctional derivatizing reagents containing cationic groups. The resulting dispersion of derivatized polysaccharide may be used directly without further purification, e.g., as an additive for paper pulp which improves retention of pigment and paper strength.

    Abstract: Novel liquid cationic starch derivatives and methods for their preparation are described. The derivatives, prepared by reaction of starch with epichlorohydrin-ammonium hydroxide condensates, are useful as additives in the manufacture of paper wherein they increase the retention of inorganic pigments by the cellulose pulp and strengthen the resulting paper.
