  • 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.
  • 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.
  • What is polyacrylamide?
  • Polyacrylamide is a term that has various definitions. For our purposes here, we will simply term polyacrylamide as a polymer that contains an acrylamide monomer at some level. Polyacrylamides make up the largest group of polymers in comparison to other synthetic polymeric polyelectrolytes.
  • How does temperature affect polyacrylamide cations?
  • The polymerization was slowed down, leading to excess monomer, and the molecular weight was reduced. Based on the response surface methodology in Figure 10 a,b,e,f, when the reaction temperature increased from 55 °C to 60 °C, the molecular weight of polyacrylamide cations increased rapidly, and reached its maximum at 60–62 °C.
