摘要： Methods for synthesizing acryloyl-based copolymers. The methods include providing a free radical initiator with a solution including monomeric repeating units, a chain transfer agent, and an organic solvent to form a reaction mixture, in which the monomeric repeating units include a first monomeric repeating unit having formula (1a), a second monomeric repeating unit having formula (1b) or (1d), and optionally a third monomeric repeating unit having formula (1c): in which the organic solvent is chosen from monoethylene glycol, ethanol, toluene, or combination thereof; and (B) initiating a polymerization reaction in the reaction mixture to polymerize the monomeric repeating units, thereby synthesizing the acryloyl-based copolymer. Methods for inhibiting formation of clathrate hydrates include contacting a fluid with the acryloyl-based copolymer synthesized in the reaction mixture.

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： 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 fuel cell membrane is a polymer electrolyte (or polyelectrolyte) membrane formed from a blend of sulfonated poly(ether ether ketone) (SPEEK) and phosphonated polysulfone in the ester form (PPSU-E), where the sulfonated poly(ether ether ketone) and the phosphonated polysulfone each form about 50 wt % of the polyelectrolyte membrane. The polyelectrolyte membrane is made by dissolving a mixture of SPEEK and PPSU in the ester form (PPSU-E) in dimethylacetamide (DMAc) at room temperature to form a solution. The SPEEK/PPSU-E mixture has a concentration of between about 10 wt % and about 15 wt % in the solution. The solution is then stirred and left to release air bubbles therefrom. The DMAc is then evaporated from the solution, leaving the resultant polyelectrolyte membrane, which is then washed and dried.
