In response to environmental guidelines, a low phosphonic multipolymer was synthesized and its corrosion inhibition effi-ciency to brass in synthetic water was investigated through weight loss measurements and electrochemical tests. It showed that thesynthesized inhibitor decreased corrosion under the conditions tested. Potentiodynamic polarization curves indicated that the new in-hibitor acted as an anodic inhibitor, reducing metal dissolution. The composition of protective films formed on the brass was studied byenergy-dispersive X-ray analysis (EDX). The inhibition effects were due to the formation of a protective film of the multipolymer in-hibitor on the metal surface.
