  • What is high molecular weight partial hydrolysis polyacrylamide (HPAM)?
  • High molecular weight partial hydrolysis polyacrylamide (HPAM) is widely used in the oil recovery, and however, these high molecular weight HPAM will experience a rapid degradation when Fe 2+ was existed in the system. Some studies have implied it was a radical assisted decomposition process.
  • Which polymer is used to produce partially hydrolyzed polyacrylamide (HPAM)?
  • PAM is used to produce partially hydrolyzed polyacrylamide (HPAM), which is linear, anionic, water-soluble, stable, polymeric, and high molecular weight chain of acrylamide (C 3 H 5 NO) monomers (Bao et al., 2010; Braun et al., 2025; Liu et al., 2016; Xiong et al., 2018).
  • Why is polyacrylamide a high molecular weight polymer?
  • As the representative material, high molecular weight partially hydrolyzed polyacrylamide, because of its extremely high molecular weight and the electrostatic repulsion between the negative carboxylate charges along the polymer chain [ 1, 2 ], it can directly increase the viscosity of the oil recovery water and pump out feasibly.
  • Does the molecular weight of hydrolyzed polyacrylamide affect cross-linking reaction?
  • The influence of the molecular weight ( Mw) of hydrolyzed polyacrylamide (HPAM) on the cross-linking reaction of HPAM/Cr 3+ and the transportation of HPAM/Cr 3+ in microfractures is systematically studied using viscometry, ultraviolet–visible absorption spectrophotometry, and displacement experiment with a visual microfractured model.
