    Abstract: An aminoalkyl imidazolines of the formula: having p-octyloxy-, p-dodecyloxy-, or p-octadecyloxy-phenyl pendants as hydrophobes, for use to mitigate mild steel corrosion. An electron-rich aromatic ring, in conjugation with an amidine motif, imparts increasing corrosion inhibition efficiencies with an increasing hydrophobe chain length. X-ray photoelectron spectroscopy confirms the formation of an aminoalkyl imidazoline film on a metal surface prior to reaching a critical molar concentration.

    Abstract: The poly(zwitterion-alt-sulfur dioxide) copolymer includes a structural unit having the structural formula: The copolymer is made by cocyclopolymerizing 3-(N,N-diallyl,N-carboethoxymethylammonio)propanesulfonate with sulfur dioxide to obtain an intermediate polyzwitterion (PZ) copolymer, which is hydrolyzed to form the copolymer. The copolymer may be converted to a poly(electrolyte-zwitterion) by treatment with a base, such as sodium hydroxide.

    Abstract: A symmetrically substituted cationic monomer and its corresponding cationic polyelectrolyte (CPE) (+) bearing two identical (diethoxyphosphoryl)propyl pendent groups on repeating pyrrolidinium units. Phosphonate ester hydrolysis in (CPE) (+) forms a pH-responsive cationic polyacid (CPA) (+). The (CPA) (+) is converted under pH-induced transformation into a polyzwitterion acid (±) (PZA) or a polyzwitterion/anion (±−) (PZAN) or a polyzwitterion/dianion (±=) (PZDAN) or a polyzwitterion/trianion (±≡) (PZTAN).

    Abstract: A method for inhibiting corrosion of a metal article in contact with a solution including an acid includes adding to the solution a corrosion inhibitor in an amount of 1 to 500 parts per million (ppm) based on the total number of parts by mass of the solution, thereby adsorbing the corrosion inhibitor onto the surface of the metal article via at least one interaction to form a barrier layer in the form of a composite. The at least one interaction comprises a physisorption, a chemisorption, and a retro donation. The corrosion inhibitor has a formula (I) where n is any integer from 8 to 21 inclusive and R1, R2, R3, R4, and R5 are each independently selected from the group consisting of a hydrogen atom, a hydroxyl group, an optionally substituted alkyl, an optionally substituted cycloalkyl, and an optionally substituted alkoxy.
