  • What is a polyacrylamide in papermaking?
  • In the 1950s a new family of papermaking additives was developed – polyacrylamides . Polyacrylamides are made by polymerising acrylamide solution using free-radical catalysts, to form a linear, non-ionic polymer .
  • How were polyacrylamides made?
  • In the 1950s a new family of papermaking additives were developed — polyacrylamides. 1 Polyacrylamides are made by polymerising acrylamide solution using free-radical catalysts, to form a linear, non-ionic polymer. 2 Download to read the full chapter text These keywords were added by machine and not by the authors.
  • Is polyacrylamide a coagulant or a dispersant?
  • This is very much system-dependent. Most solution polyacrylamides fall into the category of coagulants, dispersants, fixatives, and paper strength resins due to the limits of the chemistry, desired active polymer content, desired charge, molecular weights, and shelf-life.
  • 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.
