  • What is polyacrylamide (PAM)?
  • PAM, or anionic Polyacrylamide, is a very long chain, high molecular weight organic polymer produced from natural gas, with characteristics which make it useful as a soil amendment to control runoff and soil loss.
  • Is nionic polyacrylamide a hazard?
  • nionic polyacrylamide.NICNAS has assessed anionic polyacrylamide in an IMAP Tier 1 assessment and considers it a po ymer of low concern1 . In addition, based on an assessment of environmental hazards, NICNAS also identified anionic polyacrylamide as a chemical of low concern to the envi
  • Is polyacrylamide a cationic or nonionic polymer?
  • Degradable or bioaccumulative. Anionic polyacrylamide has low acute toxicity. Co-chemical properties Polyacrylamide polymers can exist in cationic, anionic or nonionic forms, depending on their ionic charge. Nonionic forms of polyacrylamide are generated from basic polymers.
  • Does anionic polyacrylamide biodegrade?
  • ent only.1 BACKGROUNDAnionic polyacrylamide is the copolymer of acryl mide and acrylic acid. No studies on the environmental fate of polyac ylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biode rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer
