  • Is cationic polyacrylamide hydrophilic?
  • However, a cationic polyacrylamide itself contains a large number of hydrophilic amide groups that cannot drive the transformation of surface water adsorbed on and absorbed in the sludge flocs into free water that can be separated and removed.
  • Does the flocculation mechanism of hacpam have a hydrophobic association Bridging effect?
  • Theoretically, the flocculation mechanism of HACPAM, in addition to the adsorption and electrical neutralization of CPAM, also has a hydrophobic association bridging effect enhanced by the introduction of hydrophobic groups.
  • What is a strong viscosity maximum for terpolymers incorporating AA?
  • For terpolymers incorporating AA, a strong viscosity maximum is observed at intermediate pH values (pH 4−6) where the AA groups are partially ionized and at SDS concentrations close to the critical micelle concentration.
