Abstract
The effect of addition of hyperbranched poly(amide-ester) (HPAE) generations 3 and 4 (AG3 and AG4) on the corrosion of steel in hydrochloric acid solution has been studied by weight loss measurements and quantum chemical calculations.  The inhibition efficiency depended on the concentration of the hyperbranched poly(amide-ester). The experimental results suggest that these compounds are efficient corrosion inhibitors and the inhibition efficiencies increase with increasing their concentrations. The computed quantum chemical properties show good correlation with experimental inhibition efficiencies. Results obtained showed that hyperbranched poly(amide-ester) (HPAE) generations 4 is the best inhibitor, and the protection efficiency follows the order: AG4 > AG3. Inhibition efficiency was found maximum up to 97.05% for AG4 at the highest concentration (1000 ppm).
