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.

Use of multiple charged cationic compounds derived from primary amines or polyamines for microbial fouling control in a water system

Surface-modified nanoparticles and surfactants are used in compositions and methods for enhancing hydrocarbon recovery from subterranean formations.

Surface-modified nanoparticle compositions and related applications in subterranean hydrocarbon recovery

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:

Oleyl propylenediamine-based corrosion inhibitors

A composition is disclosed that may include an adhesive agent and a release aid. A Yankee dryer coating is also disclosed that may include a release aid. The release aid may include a cationic polymer salt that is a reaction product of a polyamine or a polyalkyleneimine and a substituted alkyl trialkyl quaternary ammonium salt. Also provided are methods of treating and creping paper.

Quaternary cationic surfactants and polymers for use as release and coating modifying agents in creping and tissue papers

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:  

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.

Quaternary cationic polymers

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 &#x3b1;,&#x3b2;-unsaturated carbonyl compound or from polyamines through both an aza-Michael addition with an &#x3b1;,&#x3b2;-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.

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).
