  • 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.
  • Can sodium polyacrylate superabsorbent polymers be recycled?
  • In contrast, few studies have examined recycling of the sodium polyacrylate superabsorbent polymers. Mechanical recycling is not feasible because the crosslinks prevent melting. Decrosslinking has been reported using ozonolysis 16, though not for the purposes of mechanical recycling.
  • What is a super absorbent polymer?
  • Super-absorbent polymer refers to a three-dimensional network polymer, an organic or inorganic material that is swellable in water but insoluble in water, capable of absorbing up to about 5000 times its weight in an aqueous solution.
