ABSTRACT:
Multifunctional scale inhibitor compositions, alone or together with polymeric structures, are described which are characterized by having, in addition to a phosphonomethylamino group, a sulfonic acid and/or carboxylic acid group. By incorporating several types of functional groups into a single molecule, control of scale formation and deposition under more severe conditions than normally encountered can be attained.
