Abstract

Particulate materials in aqueous media such as heat exchange systems are dispersed by introducing into the system a polymer blend comprising about 50 to 99% by weight of (A) a water-soluble, dissociating, low molecular weight polymer of at least one alpha, beta-monoethylenically unsaturated carboxylic acid, and about 50 to 1% by weight of (B) a water-soluble, dissociating, lower molecular weight polymer selected from (1) vinyl aromatic polymers and (2) polymers of 2-acrylamido-2-methylpropanesulfonic acid. A typical polymer blend comprises, in neutralized form, (A) polyacrylic acid terminated with thioglycolic acid and (B) a polymer of sulfonated styrene and maleic anhydride.
