ABSTRACT:
A water soluble isopropenylphosphonic acid copolymer composition and method of use thereof are disclosed. The copolymer comprises repeat units (a) of the formula: ##STR1## wherein X=OH or OM, wherein M is a cation, and repeat units (b) of the formula: ##STR2## wherein R.sub.1 and R.sub.2 are independently hydrogen, C.sub.1-10 linear or branched alkyl, phenyl or alkyl substituted phenyl. The copolymers are effective in inhibiting the precipitation of scale forming salts and also act to inhibit corrosion in boiler water systems.
