Synthesis of New 1,2,4-Triazole Containing Copolymers and Their Corrosion Inhibition оf Mild Steel in Acidic Medium

In this study, new synthesized triazole-containing copolymer derivatives were investigated. The title compounds were identified using Fourier-transform infrared spectroscopy, proton nuclear magnetic resonance spectroscopy, and carbon-13 nuclear magnetic resonance spectroscopy. The inhibitory effects of the synthesized compounds (1, 2, and 5) on the corrosion of mild steel in a solution containing 0.5 M H₂SO₄ were studied using also the electrochemical polarization technique (Tafel plots). The resulted values of corrosion parameters showed the efficacy of corrosion inhibition by raising the concentration of organic corrosion inhibitors of mild steel in 0.5 M H₂SO₄ solution at 295 K.
