  • 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 a water soluble polymer?
  • Polyacrylamide (PAM) is a synthetic water-soluble polymer, which is also commonly applied as a viscosity modifier in cementitious materials [ 11, 12 ]. Owing to its high molecular weight (up to 30 million) as well as the -COOH and -CONH 2 groups present in its structure, PAM confers thickening properties [ , , , , ].
  • What is the formula for polyacrylamide?
  • Polyacrylamide is a linear polymer chain with recurring acrylamide subunits. Its formula can be expressed as (C 3 H 5 NO) n, illustrating the repeating nature of its constituent monomers. The synthesis of polyacrylamide typically involves the polymerization of acrylamide (C 3 H 5 NO) monomers, often through a free radical mechanism.
  • What is the standard state of polyacrylamide?
  • Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?
  • ) Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -).
