New kind of water soluble hyperbranched polyamide ester (HPAE) synthesized using trimethylol propane as a precursor via Michael addition reaction with diethanolamine. The chemical structure of the prepared polymers was determined by FT-IR. The inhibitive effect of HPAE on the corrosion of steel in 1 M HCl solution has been investigated using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The results indicated that HPAE inhibited the corrosion of steel and the extent of inhibition increased with HPAE concentrations. Potentiodynamic polarization data suggests mixed-mode of corrosion inhibition.
