Box 83145/115, Islamic Republic of Iran Y1 - 2022 PY - 2022 VL - 41 IS - 3 SP - 97 EP - 110 KW - Poly (methyl methacrylate) KW - maleic anhydride KW - Phenylhydrazine KW - 4- aminobenzoic acid KW - Corrosion inhibitor KW - Mild steel DO - N2 - In this study, phenylhydrazine and 4-aminobenzoic acid were reacted with co-polymer (methyl methacrylate / maleic anhydride) and in the following, used as a corrosion inhibitor of low carbon steel. The chemical structure of copolymers was identified by spectroscopy of FT-IR and H-NMR, also titration and viscosity test. the amount of thermal resistance synthesized copolymers was investigated by thermal analysis of TGA, DTG and DSC. the results indicated that the thermal resistance of P (MMA-MA) / PhH and P (MMA-MA) / ABA in comparison with the (MMA-MA) has increased. In the following, via electrochemical potentiodynamic polarization tests, EDX and FE-SEM, the effectiveness and inhibition capability of copolymers in hydrochloric acid of 0.5 mol was investigated. The results showed that corrosion rate of co-polymers are (MMA-MA)
