Zusammenfassung:	A method for thickening, stabilizing, controlling mobility or enhancing water retention in electrolyte-containing or non-electrolyte-containing aqueous media employs neutrally-charged polyamphoteric graft copolymers of polysaccharides with zwitterionic monomers or cationic/anionic monomer pairs. These polyampholytes are characterized by their unique resistance to loss of intrinsic viscosity in the presence of electrolytes. These polyampholytes may be prepared by an inverse emulsion method of graft copolymerization. Once such electrolyte-tolerant polyampholyte is a novel composition prepared by graft copolymerization of guar gum.
