  • What is hydrolyzed polyacrylamide (HPAM)?
  • Sci. 2019, 136, 47793. ABSTRACT Partially hydrolyzed polyacrylamide (HPAM) is the water-soluble polymer most often used in flooding applications in the petroleum industry. However, in aqueous solutions at high temperatur...
  • Does polyacrylamide hydrolyze under acidic conditions?
  • As reported by Muller et al., polyacrylamides undergo hydrolysis under acidic conditions to yield poly (acrylamide-co-acrylic acid). Amide groups will completely hydrolyze under conditions of appropriately low pH, and polymer weight will remain relatively stable during hydrolysis, as the following formula , , .
  • How is partially hydrolyzed polyacrylamide wastewater treated?
  • Yongrui, P., et al. Treatment of partially hydrolyzed polyacrylamide wastewater by combined Fenton oxidation and anaerobic biological processes. Chem. Eng. J. 273, 1–6 (2015).
  • Does HBR hydrolyze polyacrylamide?
  • It was also reported that HBr acts as a catalyst for the hydrolytic scission of amide bonds, resulting in a scission and MW chain reduction. Muller et al. , proposed that polyacrylamides would hydrolyze under slightly acidic conditions (pH = 4), and reported that the molecular weight of the polymer remained relatively stable during hydrolysis.
