Polyelectrolyte polymers¡ªTypes, forms, and function

The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers [80] .

Polyacrylamide - Wikipedia

Article Talk Read Edit View history Tools From Wikipedia, the free encyclopedia Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated.

water-based polymer drilling fluid and method of use

Water-Based Polymer Drilling Fluid and Method of Use

Oct 11, 2006 A water-based drilling fluid comprises a polymer which is a non-ionic polymer or an anionic polymer. The polymer can be a polyacrylamide. The fluid is used for drilling subterranean formations containing heavy crude oil and bitumen-rich oil sands, and may comprise additional fluid components.

Support Document for the Third Six-Year Review of Drinking

Acrylamide monomer is used to make anionic and cationic copolymers, as well as nonionic polyacrylamide. Nonionic polyacrylamide may also be hydrolyzed to form an anionic polymer. Epichlorohydrin is used to make various cationic copolymers, notably epichlorohydrin-dimethylamine copolymer (epi-DMA). Epichlorohydrin polymers that contain amine

Adsorption of Different Ionic Types of Polyacrylamide on

The polymers investigated were nonionic polyacrylamide (NPAM), anionic polyacrylamide (APAM) and cationic polyacrylamide (CPAM). This is because polyacrylamide-based polymers are commonly used in various water treatment industries [9,31,32,33,34]. Magnafloc 155 (APAM 10%), Magnafloc 5250 (APAM 30%), Magnafloc 351 (NPAM), Zetag 8110 (CPAM 10%

Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization. The effects of the monomer concentration, initiator concentration, reaction time, feeding temperature and reaction temperature on the molecular weight were systematically investigated through

Polyacrylamide Soil Conditioners: The Impact on

Nonionic polyacrylamide has a strong hydrophilic character, greater than other nonionic, water-soluble polymers. Despite being described as nonionic synthetic polyacrylamides obtained as a result of polymerization or copolymerization of acrylamides, often contain in their macromolecules about 1¨C3% of anionic groups . These groups are formed

Journal of agricultural and food chemistry, 56 (8), 2773-2779 (2008-03-21) Linear anionic polyacrylamide (PAM) has been used in irrigation practices as a flocculating agent to minimize water losses through seepage in earthen canals. The stability of PAM is of concern because of the possibility of acrylamide (AMD) monomer release during.
