  • Is polyacrylamide ionic or nonionic?
  • Polyacrylamide [IUPAC poly (2-propenamide), hereafter PAM] is a polymer (–CH2CHCONH2–) formed from acrylamide subunits. Polyacrylamide with only acrylamide monomers is nonionic; other monomers such as acrylate or 2-acrylamido-2-methylpropane sulfonate (AMPS) can be copolymerized at various percentages to form anionic PAM.
  • What type of polyacrylamide is used in oil industry?
  • The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
  • What is anionic polyacrylamide (Apam)?
  • 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
  • What is an anionic polyacrylamide used for?
  • There is a wide range of uses for anionic polyacrylamides and these include wastewater treatments aids, retention aids, and strength agents in papermaking, hydraulic stimulation, and enhanced oil recovery in oil field applications, mineral processing, and as soil conditioners in agricultural uses.
