  • What are cationic polyacrylamide copolymers (PAMS)?
  • Keywords: Transformation, Sludge-amended soil, Outdoor lysimeter study Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management.
  • 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.
  • Are cationic polyacrylamide copolymers harmful to the environment?
  • Environ Sci Eur. 2018; 30 (1): 16. Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.
  • What type of polyacrylic acid is used in ionic Pam?
  • Anionic PAM usually contains about 5% polyacrylic acid groups formed by copolymerization of acrylamide and acrylic acid monomers or by hydrolysis of PAM homopolymer under conditions to convert some of the amide groups to carboxylate salts. PAM with as much as 50% acrylic acid is used.
