ABSTRACT:
A composition for treating an aqueous system to inhibit deposition of scale caused by scale-forming impurities in the system which comprises (A) a hydrolysed homopolymer of maleic anhydride having a weight average molecular weight of 400 to 800 or a water-soluble salt thereof and (B) a carboxyl-containing acrylic polymer having a weight average molecular weight of 800 to 9500 selected from a polyacrylic acid, a polymethacrylic acid, a copolymer of at least two acrylic monomers, one of the monomers being acrylic acid of methacrylic acid, a copolymer of acrylic acid or methacrylic acid with a vinyl carboxylate or a styrene, a phosphinoacrylic acid telomer or a phosphinomethacrylic acid telomer, of a water-soluble salt of the carboxyl-containing acrylic polymer.
