Water soluble polymers are provided comprising repeat unit moieties (a) and (b) wherein the repeat unit moietyn (a) comprises the structure,n wherein X = OH or OM, wherein M is a cation, and the repeat unit moiety (b) comprises the structuren wherein R 2 is H or alkyl of from 1-3 carbon atoms, and R, is hydroxy, hydroxylated alkoxy, or amide, or a water-soluble salt form thereof. n These polymers are useful in controlling the deposition of scale-imparting precipitates and in inhibiting corrosion of metal parts. |
