Abstract

The accumulation of scale in an aqueous system is inhibited by the addition of a composition comprising a copolymer of maleic acid or anhydride and vinyl sulfonic acid and an organic phosphonate such as aminotri(methylene phosphonic acid) hydroxyethylidene diphosphonic acid, or a water soluble salt thereof.
