  • Which polymer thickening agent is a cationic polyacrylamide?
  • Zhang et al. , synthesized the polymer thickening agent DXGY-1, which is a cationic polyacrylamide. Its viscosity retention ratio in 12% HCl + 3% HF reached 82%. Liu et al. , synthesized a copolymer from AM, DMDAAC, and AMPS monomers and a cationic monomer X.
  • Do polymer adsorption kinetics and polymer conformation control particle flocculation?
  • This was consistent with the previous study : polymer adsorption kinetics and polymer conformation are more important than the amount of adsorbed polymer in controlling the extent of particle flocculation.
  • How does pH affect polyacrylamide hydrolysis?
  • Muller et al. , proposed that polyacrylamides would hydrolyze under slightly acidic conditions (pH = 4), and reported that the molecular weight of the polymer remained relatively stable during hydrolysis. Thomas et al. , investigated the effects of different pH conditions and reaction times on the hydrolysis process.
  • Does anionic polyacrylamide improve coagulation-flocculation process?
  • Aguilar, M. I. et al. Improvement of coagulation-flocculation process using anionic polyacrylamide as coagulant aid. Chemosphere 58, 47–56 (2005). Muller, G., Fenyo, J. C. & Selegny, E. High molecular weight hydrolyzed polyacrylamides.
