  • What is a cationic polyacrylamide (CPAM) dispersion?
  • A cationic polyacrylamide (CPAM) dispersion, the copolymer of acrylamide (AM) and acryloyloxyethyltrimethyl ammonium chloride (DAC), has been synthesized through dispersion polymerization in aqueous ammonium sulfate ( (NH4)2SO4) solution.
  • 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 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 .
  • Can cationic polyacrylamide be used in oilfield wastewater treatment?
  • Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
