Polyacrylamide degradation and its implications in - Nature

[1] Physicochemical properties Polyacrylamide is a polyolefin. It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone.

In this study, we synthesized polymer nanospheres with different size distributions and studied their mechanisms in enhancing the oil recovery. First, the effects of polyacrylamide nanospheres in enhanced oil recovery of heterogeneous sand-packed tubes was explored by sand-packed tube oil displacement experiments.

polymer, surfactants, oil, and water. Packaging and transport costs are greater for emulsions. Powders are very stable during storage whereas emulsions show some instabilities (physical settling, skin formation etc.). The presence of oil and surfactants involve more regulations for the emulsions than for powders. In general, emulsions outperform

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.

Polyacrylamide is a versatile chemical treatment agent in oilfield. In oil extraction it could be used as a flooding agent, water shutoff regulator, drilling fluid regulator, fracturing fluid additives, especially in cementing, completion and workover. The oil industry is the largest area of polyacrylamide applications.

Microbial degradation of polyacrylamide and the deamination

Polyacrylamide is ideal for protein separations because it is chemically inert, electrically neutral, hydrophilic, and transparent for optical detection at wavelengths greater than 250 nm. Additionally, the matrix does not interact with the solutes and has a low affinity for common protein stains.
