  • 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 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.
  • How does temperature affect the molecular weight of polyacrylamide?
  • Temperature is an important factor in controlling the molecular weights of polyacrylamides. The higher the temperature the lower the molecular weight. In the cases where very low molecular weights are desired, alternative methodologies are employed.
  • What is the molecular weight of polyacrylates?
  • Thus, the molecular weight and monomer composition can be tailored to give a variety of performance characteristics. Molecular weight for linear polyacrylates generally ranges from 1000 to 100,000 Da. Generally, the lower-molecular-weight polyacrylates act as scale inhibitors while higher molecular weights tend to be used as dispersants.
