Application of Amphoteric Polyacrylamide Solely or with

Amphoteric polyacrylamide (AmPAM) has been widely used in the wet-end of the papermaking process as a strength additive because of its unique features. AmPAM is a typical polyampholyte, carrying both basic and acid groups along the molecular chain (Dobrynin et al. 2004). Basic and acid groups dissociate in an aqueous solution.

Molecular weight of amphoteric polyacrylamide: How it

Amphoteric polyacrylamide (AmPAM) is a linear water-soluble polymer that has been applied in papermaking as an agent for flocculation, retention, filtration, and dry-strength improvement. However, AmPAM with different ranges of molecular weight (MW) have different properties in these processes.
