  • What are the different types of anionic polyacrylamide synthesis technologies?
  • The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.
  • 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 .
  • What is the molecular weight of a polyacrylamide dispersed system?
  • The resulting polyacrylamide dispersed system exhibited a molecular weight of up to 1.05 × 10 7 g·mol −1, indicating significant stability. Zhao et al . utilized dispersion polymerization to synthesize polyacrylamide, employing an aqueous solution of ammonium sulfate and sodium chloride as inorganic salts.
