Abstract

The inhibition of three ethoxylated poly (ethylene terphthalate), derived from plastic waste by reacting of PET with triethanol amine followed by reacting with polyethylene glycol, (PEG), which has different molecular weights 400, 1000 and 4000. On the corrosion of steel in 1M acetic acid solutions have been studied at different temperatures (30-60°C) by weigh loss. The inhibition efficiency for the three compounds increased with increasing of the inhibitors concentrations and temperatures. The inhibition efficiency for the three inhibitors decrease in the order (Tn= 9< 22< 90). The polarization curves indicate that these compounds act as mixed-type inhibitors. The inhibition occurs through adsorption of the inhibitor molecules on the metal surface without modifying the mechanism of corrosion process. Langmuir adsorption isotherms fit well the experimental data of dissolution and adsorption were calculated and discussed.
