ABSTRACT:
A method of inhibiting corrosion of iron and steel alloys in contact with industrial waters is claimed. The method comprises treating said waters with an effective corrosion inhibiting amount of a water soluble polymer having an average molecular weight ranging from about 2,000 to about 50,000, said polymer containing at least four mole percent of a hydroxamic acid mer unit.
