摘要： Compounds and methods of inhibiting corrosion of mild steel. Compounds disclosed herein are cationic and contain multiple functional motifs such as propargyl, cinnamaldehyde, isoxazolidine and hydrophobe. These compounds are found to be effective in inhibiting mild steel corrosion in HCl, H2SO4, NaCl and CO2-saturated environments.

摘要： Cross-linked tetrapolymers made up of different diallyl zwitterionic diallyl quaternary ammonium salt monomers, with one of them functioning as a cross-linking monomer. The cross-linked terpolymers include a repeating unit with multiple ligand centers that different metal ions can bind to. The cross-linked tetrapolymers are cationic, zwitterionic and anionic, and can be in either an acidic form or a basic form. A method of removing metal ions from an aqueous solution with these cross-linked tetrapolymers is also described.

摘要： Cross-linked cyclocopolymers made up of one or more quaternary ammonium salts and sulfur dioxide as monomers. One of the quaternary ammonium salts is also an aspartic acid derivative. The cross-linked copolymers include a repeating unit with multiple chelating centers that different metal ions can bind to. The cross-linked copolymers are zwitterionic or anionic, and can be in either an acidic form or a basic form. A method for removing metal ions from an aqueous sample with these cross-linked copolymers is also described.

摘要： 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.

摘要： 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.

摘要： A zwitterionic monomer and corresponding cyclopolymerized polyzwitterion (±) (PZ) (i.e. poly(Z-alt-SO2). Phosophonate ester hydroloysis in PZ gave a pH-responsive polyzwitterionic acid (±) (PZA). The PZA under pH-induced transformation was converted into polyzwitterion/anion (±−) (PZAN) and polyzwitterion/dianion (±=) (PZDAN).

摘要： A symmetrically substituted cationic monomer and its corresponding cationic polyelectrolyte (CPE) (+) bearing two identical (diethoxyphosphoryl)propyl pendent groups on repeating pyrrolidinium units.
