Abstract

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: ##STR1## wherein E.sup.1 comprises the repeat unit obtained after polymerization of one or more .alpha., .beta. ethylenically unsaturated monomers, selected from the group consisting of a carboxylic 3acid, lower alkyl (C.sub.1 -C.sub.6) ester or a hydroxylated lower alkyl (C.sub.1 -C.sub.6) ester of such carboxylic acid, and amide forms thereof; E.sup.2 comprises the repeat unit obtained after polymerization of one or more .alpha., .beta. ethylenically unsaturated monomer containing a sulfonic acid functionality; R.sup.1 is a hydrogen or a lower (C.sub.1 -C.sub.3) alkyl; R.sup.2 is --CH.sub.2 -- O--or --C(.dbd.O)--O--; R.sup.3 is --(--CH.sub.2 --CH(--CH.sub.2 --OH)--O--)--.sub.n ; n is an integer greater than 1; and R.sup.4 is hydrogen, 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.
