  • What is nonionic polyacrylamide (NPAM) gel?
  • Nonionic polyacrylamide (NPAM) gel was prepared for in-depth profile control. A compact three dimensional network structure was formed in the bulk gel system. Retention, adsorption and bridging across the pore throats occur in high permeability zones. The NPAM gel shows superior high temperature resistant. °C.
  • Can nonionic polyacrylamide be used as a gel fracturing fluid?
  • Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.
  • Which polyacrylamide gel has peaks at neutral pH?
  • The polyacrylamide gels herein at neutral pH had peaks that corresponded to polyacrylamide spectra in literature [ 64, 65 ], including peaks at 1428 cm −1 (C–N stretching, or Amide III), 1617 cm −1 (–NH 2 bending, or Amide II), and 1670 cm −1 (C–O stretching, or Amide I) (Fig. 5 a).
  • What is an anionic polyacrylamide?
  • Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
