Anionic Poly-Acrylamide (aPAM)

ANIONIC POLYACRYLAMIDE. Composition: Negatively charged copolymers of acrylamide are widely used as retention aids and dry-strength resins. However, different molecular mass ranges are used for these two roles. Anionic acrylamide copolymer retention aids typically have molecular masses in the range of 5 to 20 million grams per mole.
