ABSTRACT:
A method and composition for simultaneously controlling the deposition of scale and the formation of corrosion in a cooling water system comprising adding to the system a combination of (a) 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, and (b) a water soluble polymer characterized by the structural formula: ##STR3## wherein R.sub.1 is H or lower alkyl (C.sub.1 -C.sub.3); R.sub.2 is OH, OM, or NH.sub.2 ; M is a water soluble cation; R.sub.3 is a hydroxy substituted alkyl or alkylene radical having from 1 to 6 carbon atoms or a non-substituted alkyl or alkylene radical having from 1 to about 6 carbon atoms; X is an anionic radical; Z is H or hydrogens or a water soluble cation or cations which together counterbalance the valence of X, and a is 0 or 1.
