摘要： A cationic polymer salt composition is provided that includes a reaction product derived from reaction of a polyamine or a polyalkyleneimine and a substituted alkyl trialkyl quaternary ammonium salt. Also provided are surfactant compositions. The compositions may also include carriers, such as water, methanol, ethanol, propanol, isopropanol, butanol, isobutanol, monoethyleneglycol, an ethyleneglycol monobutyl ether, and hexylene glycol.

摘要： Disclosed are oleyl propylenediamine-based compounds used in compositions and methods for inhibiting corrosion. The method comprises introducing into a fluid source a composition comprising one or more oleyl propylenediamine-based compounds comprising Formula I: wherein Y1, Y2, and Y3 independently are hydrogen or a substituent of Formula (II): wherein V is —O— or —NH—, W is optionally present and is a linear or branched C1-10 aliphatic group, X is —H, —NZ3+, —COOH, —SO3H, —OSO3H2, —PO3H, —OPO3H2, or a salt thereof, each Z independently is hydrogen or a linear or branched C1-20 aliphatic group optionally interrupted or substituted with one or more oxygen atoms, and R is hydrogen or methyl, provided that at least one of Y1, Y2, or Y3 is a substituent of Formula (II).

摘要： Disclosed herein are the methods of using specific di-cationic or multiple charged cationic compounds, which are derived from primary amine or polyamines through an aza-Michael addition with an α, β-unsaturated carbonyl compound or from polyamines through both an aza-Michael addition with an α, β-unsaturated carbonyl compound and a ring-opening reaction with an epoxide, in a fouling control composition to reduce microbial and/biofilm growth in a water system. The disclosed methods or compositions are found to be more effective than those methods or compositions including commonly used single quaternary compounds for reducing microbial or biofilm growth in water systems.

摘要： An acrylamide-based polymer which contains one or more multiquaternized (“multiquat”) monomer unit(s) is provided. The acrylamide-based polymer can be used in a papermaking process to reduce pitch and stickies deposition, improve retention and drainage, and enhance dry strength properties of paper. Also included is a method of controlling pitch and stickies deposition in papermaking comprising treating pulp slurry with an acrylamide-based polymer which contains one or more multiquaternized (“multiquat”) monomer unit(s).
