  • What is partially hydrolyzed polyacrylamide (PHPA)?
  • Partially hydrolyzed polyacrylamide (PHPA), consisting of neutral acrylamide and anionic acrylate groups, is suitable for use in water with <25,000 mg/L TDS 12, 15.
  • What does partially hydrolyzed polyacrylamide mean?
  • What Does Partially Hydrolyzed Polyacrylamide Mean?
  • Partially hydrolyzed polyacrylamide (PHPA) is a widely used polymer in the oil and gas industry due to its lesser cost and good water solubility. PHPA is used as a functional additive in water-based drilling fluids.
  • What is hydrolyzed polyacrylamide (HPAM)?
  • Hydrolyzed polyacrylamide (HPAM), a derivative resulting from the hydrolysis of PAM, demonstrates significant thickening capabilities in freshwater and at relatively lower temperatures (<75 °C) due to strong intra- and inter-chain electrostatic repulsion of carboxylate groups 14.
  • Are aqueous solutions of partially hydrolyzed polyacrylamides used in deep foundations?
  • Since the early 1990s, aqueous solutions of partially hydrolyzed polyacrylamides (PHPA) also have been used for the construction of deep foundations in many different countries (e.g., Ata and O’Neill 1997; Lam and Jefferis 2014b). PHPA is a synthetic polymer comprising repeating units of acrylamides and acrylates.
