  • 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 .
  • 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.
  • Can hydrophobic associative polyacrylamide be polymerized by aqueous dispersion polymerization?
  • Hydrophobic associative polyacrylamide synthesized by aqueous dispersion polymerization can be polymerized using cationic monomers in combination with acrylamide and hydrophobic monomers, as well as copolymerized with anionic monomers alongside acrylamide and hydrophobic monomers.
  • What is dispersion polymerization?
  • Dong et al . were the first to use dispersion polymerization technology to prepare a hydrophobic association polyacrylamide derivative with good water solubility and a relative molecular mass reaching over a million using monomers such as acrylamide.
