A polymer and method of controlling corrosion and the formation and deposition of scale imparting compounds in water systems is disclosed. The polymer has the general structure: Image wherein E1 comprises the repeat unit obtained after polymerization of one or more .alpha., .beta. ethylenically unsaturated monomers, preferably a carboxylic acid, lower alkyl (C1-C6) ester or a hydroxylated lower alkyl (C1-C6) ester of such carboxylic acid, or amide forms thereof; E comprises the repeat unit obtained after polymerization of one or more .alpha., .beta. ethylenically un- saturated monomer containing a sulfonic acid functionality; R1 is a hydrogen or a lower (C1-C3) alkyl; R is -CH2-O- or -C(=O)-O-; R3 is -[-CH2-CH(-CH2-OH)-O-]-n; n is an integer greater than 1; and R4 is hy- drogen, or C1-C20 alkyl; and x is the molar percentage being between 1- 98 molar %, y is the molar percentage being between 1-98 molar %, z is the molar percentage being between 98-1 molar %, wherein the sum of x, y and z equal 100%. This polymer may also be used in concert with topping agents.
