Polyacrylamide | chemical compound | Britannica
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 (C3H5NO), a compound obtained by the hydration of acrylonitrile.
Polyacrylamide - Wikipedia
Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.
Polyacrylamide - an overview
Acrylamide release in drinking water mainly comes from the residual monomer of polyacrylamide, especially during the treatment process [1–3]. The use of polyacrylamides as a chemical grouting agent and soil stabilizer for the construction of tunnels, sewers, wells, reservoirs, and dams can also be a source of release to drinking water supplies.
Polyacrylamide - Safe Cosmetics
Polyacrylamide is used as a stabilizer and binder in lotions and other products. Though it is not a concern in itself, it is made up of repeating molecules of acrylamide, which is a strongly suspected carcinogen and has been linked to mammary tumors.

Polyacrylamide - an overview
Polyacrylamide gel electrophoresis (PAGE) was performed at alkaline pH under non-denaturing conditions. The separating and stacking gels were respectively 9% and 4% of acrylamide; buffer solutions were: 50 mM Tris-HCl (pH 9.5) for separating gel, and 18 mM Tris-HCl pH 7.5 for stacking gel; the electrode reservoir solution was 25 mM Tris, 190 mM

Effect of Polyacrylamide Application on Runoff, Erosion,
All measurements for the chemical elements were carried out according to standard procedures. Experimental treatments consisted of three appli- cation rates of PAM (0.5, 1.0, and 2.0 g m âˆ’2 )and two molecular weights of PAM (12 and 18 Mg mol âˆ’1 ), with a treatment without PAM application as the con- trol.
