polyacrylamide degradation and its implications

Polyacrylamide degradation and its implications

High MW anionic PAM is also the most commonly applied polymer in enhanced oil recovery applications; the use of surfactant-polymer flooding can increase oil recovery by 5¨C30% 14 and in some cases...

water soluble polymer flocculants: synthesis

Water Soluble Polymer Flocculants: Synthesis

Polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly (vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7

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] .

Synthesis and properties of poly(acrylamide-co-N

A new anionic polymer poly (acrylamide-co-N-vinylpyrrolidone-co-sodium p-styrene sulfonate) (abbreviated as PANS) is synthesized by using acrylamide (AM), N-vinylpyrrolidone (NVP) and sodium p-styrene sulfonate (SSS) as monomers and used as filter loss agents.

ANIONIC POLYACRYLAMIDE - Santos

Synonyms: Anionic polyacrylamide 3 PHYSICO-CHEMICAL PROPERTIES Polyacrylamide polymers can exist in cationic, anionic or non-ionic forms, depending on their ionic charge. The non-ionic form of polyacrylamide is generated from the basic polymerisation of acrylamide. Anionic polyacrylamide polymer can then be formed from the hydrolysis of the

Synthesis, characterization and properties of an anionic

An anionic polymer P (ANAN) of acrylamide, N-vinyl-2-pyrrolidone and 2-acrylamide-2-methylpropanesulfonic acid was synthesized through free radical polymerization and initiated by 2,2¡ä-Azobis (2-methylpropionamide) dihydrochloride as an anti-high temperature and anti-calcium and magnesium contamination fluid loss control additive for water-based drilling fluid. The P (ANAN) was characterized

Synthesis of novel modified acrylamide copolymers

In this paper, acrylamide copolymers were used as coagulant with cationic, anionic groups or both of them simultaneously. Consequently, in order to clarify the relationship between inhibitive properties, sedimentation volume measurement, SEM (scanning electron microscope), XRD (X-ray diffraction) and contact angle were adopted.

effect of surfactants on the performance of water-based

Effect of Surfactants on the Performance of Water-Based

Cationic and anionic surfactants affected the rheological behavior of sodium bentonite suspensions by several mechanisms. In strongly acidic media, where the pH < 4, the surfactants have clear effect on the stability of the card-house structure. The cationic surfactant promoted disintegration of the card-houses.
