  • What is polyacrylamide (PAM)?
  • Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 × 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).
  • Is polyacrylamide ionic or nonionic?
  • Polyacrylamide [IUPAC poly (2-propenamide), hereafter PAM] is a polymer (–CH2CHCONH2–) formed from acrylamide subunits. Polyacrylamide with only acrylamide monomers is nonionic; other monomers such as acrylate or 2-acrylamido-2-methylpropane sulfonate (AMPS) can be copolymerized at various percentages to form anionic PAM.
  • How to improve degradable polyacrylamide or hydro soluble polymers?
  • From a chemical point of view, one of the most interesting processes to obtain improved degradable polyacrylamide or hydro soluble polymers is the initiation of polymerization with Ce 4+ ions using an alcohol as reducing agent.
  • Can polyacrylamide be bioremediated?
  • Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed.
