Cationic polysaccharide derivatives are prepared by reacting a polysaccharide with a polycationic reagent having one polysaccharide reactive group and at least two cationic groups. Suitable reagents include polycationic alkyl, aryl, alkaryl, cycloaliphatic, or heterocyclic amines, some of which are novel compositions. The polycationic polysaccharide derivatives prepared from these reagents are useful in the manufacture of paper.
