ABSTRACT:
A method for simultaneously controlling the deposition of scale and the formation of corrosion in a cooling water system consisting of adding to the system a water soluble copolymer having the structure: ##STR1## wherein R.sub.1 is H or lower (C.sub.1 -C.sub.4) alkyl, F is H.sub.2 or O, M is a water soluble cation, R.sub.2 is (CH.sub.2 --CH.sub.2 --O).sub.n, ##STR2## or mixture of both, n is an integer of from 1 to about 40, R.sub.3 is H, lower (C.sub.1 -C.sub.4) alkyl or an acetate.
