  • 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.
  • What is acrylamide used for?
  • It is employed in the treatment of industrial and municipal wastewater. Polyacrylamides are produced by the polymerization of acrylamide (C 3 H 5 NO), a compound obtained by the hydration of acrylonitrile. Acrylamide is usually dissolved in water; it has toxic effects on the nervous system and must be handled under special protective procedures.
  • How does polyacrylamide work?
  • Polyacrylamide forms a protective coating on the skin. When polyacrylamide dries it forms a thin coating on the skin, hair, or nails. This helps to improve the appearance of makeup on the skin. In sunscreen products, polyacrylamide aids in keeping the active ingredients of the sunscreen on the skin after immersion in water.
  • Why is polyacrylamide not a polyamide?
  • It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone. Owing to the presence of the amide (CONH 2) groups, alternating carbon atoms in the backbone are stereogenic (colloquially: chiral).
