  • What is a nonionic polyacrylamide?
  • Despite being described as nonionic synthetic polyacrylamides obtained as a result of polymerization or copolymerization of acrylamides, often contain in their macromolecules about 1–3% of anionic groups . These groups are formed as a result of monomer amide groups hydrolysis.
  • What causes nonionic polyacrylamide adsorption?
  • Nonionic polyacrylamide adsorption on clay minerals is mainly caused by van der Waals forces , whereas cationic or anionic forms adsorb and bind soil particles through electrostatic forces or bridge formation between PAM charged moieties and solid surface group [1, 80].
  • What is anionic polyacrylamide?
  • Anionic polyacrylamide is polymer with a large number of negatively charged moieties in the long chains of the PAM macromolecules. It can be obtained by partial hydrolysis of polyacrylamide neutral amide groups, which is shown in (3). This process occurs under moderate temperature by adding sodium hydroxide to the PAM solution [4, 6].
  • What is a high molecular weight nonionic polyacrylamide?
  • High-molecular-weight nonionic polyacrylamides are routinely used in the mineral processing industries as thickeners and flocculants , , . 34.2.5. Polyacrylamide product forms The product types for polyacrylamides are solutions, liquids (emulsion or dispersion), and dry powders.
