ABSTRACT:
Zwitterion polygalactomannan ether derivatives are prepared by reacting a polygalactomannan gum, such as guar gum or locust bean gum, with N-(2-haloethyl)iminobis(methylene)diphosphonic acid or with a N-(alkyl)-N-(2-haloethyl)aminomethylphosphonic acid. The derivatives contain aminophosphonic acid groups (or their salts) as zwitterion substituents which consist of either one or two anionic methylene phosphonic acid groups bound to a cationic nitrogen. Modified derivatives containing non-ionic, anionic, cationic, or cationogenic substituents may also be prepared.
