OBTAINING OF OLIGOMERIC CORROSION INHIBITORS BASED ON POLYCAPROLACTAM WITH MELAMINE ADDUCT (PUM-1)

In this article, we synthesized oligomer corrosion inhibitors from polycaprolactam and acetic acid, in addition, melamine adducts was used for PUM-1 inhibitor. The structure of the obtained corrosion inhibitors was confirmed by spectroscopic techniques, as well as fundamental analysis. The inhibition efficiency of this PUM-1 brand corrosion inhibitor was determined by electrochemical methods in a 1 M HCl environment. Specially, the factors affecting the inhibition efficiency, such as the pH of the solution, the duration of time, and the concentration of the inhibitor, were studied.
