ABSTRACT:
A process and composition using hydroxyphosphonoacetic acid or its water-soluble salts in combination with certain copolymers, such as water-soluble 1-acrylamido-2-methylpropane sulfonic acid copolymers with acrylic acid or methacrylic acid, provide improved corrosion protection for iron based metal in contact with the system water of aqueous systems.
