  • 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 a polyacrylamide (PAM)?
  • 1. Introduction Polyacrylamides (PAM) are high molecular weight polymers deriving from the polymerization of acrylamide monomers. Their chemical composition and ionic character depend on the functional groups added to the acrylamide chemical moiety ( Abidin et al., 2012; Acharya et al., 2010 ).
  • Are Apam polymers toxic?
  • EOR polymers, including APAM, are generally assumed to be relatively nontoxic ( Biesinger and Stokes, 1986; Bolto and Gregory, 2007 ). However, data on impacts on aquatic species, especially marine species are very limited.
  • What is the ionicity of Apam and CPAM?
  • When two or three of the eight amido functional groups are replaced, the ionicity of the APAM or CPAM obtained is 25.0% or 37.5%, Na ions were added to APAM and Cl ions to CPAM to compensate for the charge of the ionized PMA molecules. The montmorillonite model is consistent with the Na-rich montmorillonite sample used in the QCM-D experiments.
