ABSTRACT:
New amines and amides of carboxylated polysaccharides having the nitrogen of the amido and amino groups directly attached to the polysaccharides and method of making same, based on reacting in solution a material having carboxyl-containing polysaccharides, such as carboxymethyl cellulose, with ammonium donors having the general formula >NH such as primary and secondary amine reagents and with or without a reducing agent to obtain amides or amines. These products may be used for instance in biological separations, for the immobilization of proteins, for the removal of metal ions, as thickeners, and as suspension agents.
