Fabricating an anionic polyacrylamide (APAM) with an anionic block

Considering all aforementioned factors, this study attempts to (1) synthesize the template copolymer (TPAS) with the anionic microblock structure through UTP using AM and SAS as monomers, and PAAC as template; (2) elaborate the template polymerization mechanism through the analysis of the association constant KM; (3) characterize the chemical st...

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 .

Binding of Anionic Polyacrylamide with Amidase and Laccase under 298

Amidase and laccase play a key role in the degradation process of anionic polyacrylamide (HPAM). However, the largest challenge of HPAM enzymatic degradation is whether the enzyme can bind with a substrate for a period of time. Here, the most suitable complexes, namely, Rh Amidase-HPAM-2 and Bacillus subtilis (B. subtilis) laccase-HPAM-3, were obtained by docking, and they were carried out for

Polyacrylamide | Water Treatment, Soil Stabilization & Flocculation

polyacrylamide, an acrylic resin that has the unique property of being soluble in water. It is employed in the treatment of industrial and municipal wastewater. Polyacrylamides are produced by the polymerization of acrylamide (C 3 H 5 NO), a compound obtained by the hydration of acrylonitrile. Acrylamide is usually dissolved in water; it has
