  • Can polyacrylamide aqueous dispersion be soluble after polymerization?
  • However, after polymerization, the resulting copolymer should not be soluble in the dispersion medium. The first non-ionic monomer used in aqueous media was acrylamide, which can be copolymerized with anionic and cationic monomers to produce an ionic polyacrylamide aqueous dispersion system .
  • 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 [ , , ].
  • Can an anionic polyelectrolyte be used as a stabilizer?
  • In 2010, Lu et al . utilized an anionic polyelectrolyte as a stabilizer to copolymerize acrylamide (AM) and acrylic acid (AA) in an inorganic salt solution through dispersion polymerization, which ensuing product was a smooth, spherical and poly-dispersed anionic polyacrylamide dispersion.
  • Which dispersion medium is used for cationic polyacrylamide aqueous polymerization?
  • Initially, most researchers utilized ammonium sulfate as the dispersion medium for polymerization. Zheng et al . prepared a stable cationic polyacrylamide aqueous dispersion using poly (2-methylacryloylxyethyl trimethylammonium chloride) (DMC) as the dispersion stabilizer and potassium persulfate-sodium sulfite as the initiator.
