  • What is a polyacrylamide (PAM)?
  • Polyacrylamides (PAMs) are relatively inexpensive polymers that are easily formulated to high molecular weights on the order of several million g/mol. PAM was first used in the paper industry in the mid-1950s.
  • Can high molecular weight Pam be used for degradation?
  • This paper provides a short review of current applications of high molecular weight PAM, including the potential for PAM degradation by chemical, mechanical, thermal, photolytic, and biological processes.
  • What is cationic Pam?
  • Cationic PAM is made by copolymerization of acrylamide monomers with cationic monomers (described below). Thomas L. Staples, Pronoy K. Chatterjee, in Textile Science and Technology, 2002
  • Are cationic PAMS prone to quaternary ammonium hydrolysis?
  • Most cationic moieties of cationic PAMs are also prone to prompt ester hydrolysis, also resulting in the formation of corresponding acrylate salt or acrylic acid and the release of quaternary ammonium products.
