Paper Making Polyacrylamide

Polyacrylamide (PAM) is used as paper-making additive with different molecular weight and functional groups. PAM has many functions, such as increasing filler retention, enhancing wet-dry strength of paper fibers, improving surface properties, ink adsorption, and so on.

Polyacrylamide in paper making began 30 years ago, when anionic polyacrylamide was used. Various modified polyacrylamides developed rapidly, especially the copolymerization of AM with other monomers and the grafting copolymerization of AM with starch.
