  • What is cationic polyacrylamide?
  • Cationic Polyacrylamide is white power or granule, the degree of ion is from 5% to 80%, soluble, good water solubility, can be dissolved in water at any percentage and be undissolved in organic solvents. CPAM shows characteristics of high polymer electrolyte, suitable for wastewater treatment with a negative charge and rich organic matter.
  • What type of polyacrylamide is used in oil industry?
  • The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
  • What is an anionic polyacrylamide?
  • Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
  • Do cationic polyacrylamide hydrogels have a higher interface adhesion strength?
  • Interestingly, cationic polyacrylamide hydrogels possess a higher interface adhesion strength but less bulk cohesion. These findings are helpful to comprehend molecular weight and concentration effect on polyacrylamide hydrogel performances and the relationship between hydrogel network structure and macroscopical properties.
