Abstract

In this research, the nanoparticle graft co-polymer was prepared, by reacting glycerol with terphthalic acid as a first step, and in the second step added maleic anhydride to prepare graft co-polymer by solubilization process. Fixed weights of the Poly (Terphthalic acid-co-Glycerol-G-Maleic anhydride) were mixed with different weights of acrylic acid (0.2 – 0.4 – 0.6 –and 0.8 mol) with the addition of drops of cobalt octoate to get different concentrations of the inhibitor. Carbon steel ingots were coated with these concentrations and the inhibition efficiency was calculated at different temperatures (303 –313 –323) k with a fixed time of 30 minutes. The highest results of inhibition efficiency recorded 91.41% at concentration 0.8 mol of Nano-polymer and at 303 K .
