Polyacrylamide degradation and its implications

The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1,...

polyacrylamide

Polyacrylamide

[1] Copolymers and modified polymers [ edit] Linear polyacrylamide is a water-soluble polymer. Other polar solvents include DMSO and various alcohols. Cross-linking can be introduced using N,N-methylenebisacrylamide. Some crosslinked materials are swellable but not soluble, i.e., they are hydrogels .

Cationic polyacrylamide copolymers (PAMs): environmental half

Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.

ANIONIC POLYACRYLAMIDE - Santos

Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

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

Anionic polyacrylamides hold the largest portion, as far as, market size goes, however, only being slightly ahead of cationic polymers. Anionic and cationic polyacrylamides make up roughly ~ 75% of the total polyacrylamide market, with nonionic products comprising the final ~ 25%. The largest application areas include solid-liquid separation in

Spotlight on the Life Cycle of Acrylamide-Based Polymers

Broadly speaking, polymer molecular weight reduction is progressive and continuous and is usually observed over a time span of months . Polyacrylamide copolymers, either anionic or cationic, are potentially quickly converted to corresponding polyacrylate salts by deamination or hydrolysis.

PAM (anionic Polyacrylamide) - USDA ARS

PAM (anionic Polyacrylamide) for Runoff and Soil Erosion Control. PAM, or anionic Polyacrylamide, is a very long chain, high molecular weight organic polymer produced from natural gas, with characteristics which make it useful as a soil amendment to control runoff and soil loss. The chemical when applied as a liquid solution to a freshly-tilled
