Several works have been done and more are on the pipeline on the influence of organic compounds containing polar functions on the corrosion inhibition of metals in various aqueous media. Corrosion inhibition by such compounds is generally attributed to their adsorption on the metal/solution interface. The specific action of an inhibitor depends on the nature of its interaction with metal surface, which causes a change in either mechanism of the electrochemical corrosion process or in the surface area available for the process. Thus, factors such as physiochemical properties of the inhibitors, the nature and surface charge of the metal, solution composition and pH are important considerations. Polymers function as corrosion inhibitors because of their ability to form complexes through their functional groups with metal ions which occupy large area and by so doing blanket the metal surface from aggressive anions present in solution.

“…Large numbers of organic compounds were studied to investigate their corrosion inhibition potential. For example, the effect of organic nitrogen compounds on the corrosion behaviour of iron and steel in acidic solutions is employed for their corrosion inhibiting action [3][4][5][6][7][8][9][10]. Recently, the application of surfactants as effective corrosion inhibitors has attracted the attention of many researchers.…”

“…Very few reports are available in the literature on water soluble polymers as corrosion inhibitors for oil well tubing and casing material in harsh environments. Finsagar et al studied the effectiveness of polyethyleneimines of different molecular weights as corrosion inhibitors for AISI 430 [12] and ASTM 420 [13] stainless steel in nearneutral chloride media. Gao et al [14] reported that the high inhibition efficiency of some acetylenic alcohols with a-alkenylphenones and α,β-unsaturated aldehydes is due to the surface polymerization during acid environmentally benign, easily degradable and suitable for use in both acidic and neutral media.…”

Five different water soluble terpolymers, namely polyvinyl alcohol-g-poly(acrylamidevinylsulfonate), polyvinyl alcohol-g-poly(acrylic acid-vinylsulfonate), polyvinyl alcohol-g-poly(acrylamide-vinyl benzene sulfonate), polyvinyl alcohol-g-poly(acrylic acid-vinyl benzene sulfonate) and polyvinyl alcohol-g-poly(vinylsulfonate-vinyl benzene sulfonate), have been designed, developed and tested for their efficacy to control N-80 steel corrosion in 10 % HCl, 3.5 % NaCl and simulated well water. The terpolymer characterization was carried out by FTIR. The inhibitors were tested by potentiodynamic and impedance techniques. The inhibitors were also tested in static and dynamic conditions at 55±5 °C, for 6 hours immersion period by weight loss method. Acrylamide terpolymers rendered the best inhibition efficiency in all the studied systems. The results provided a preliminary validation of the inhibitor such that they can be optimised and used for corrosion in oil and gas industries.
