  • Is polyacrylamide a cationic or nonionic polymer?
  • Recently, polyacrylamide was introduced in geotechnical engineering into the process of clay treatment . Regarding the type of polymer charge, polyacrylamide can be divided into three types: nonionic (PAM), anionic (APAM), and cationic (CPAM).
  • 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 .
  • When was polyacrylamide first used in drilling mud?
  • Polyacrylamides were first introduced as an additive to drilling muds in the 1960s. 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.
  • 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.
