Molecular weight of amphoteric polyacrylamide: How it is ...

Cationic polyacrylamide (CPAM) and cationic starch have been used as dry strength agents for many years in papermaking. However, CPAM is more suitable than cationic starch due to its lower required dosage. Recently, amphoteric polyacrylamide (AmPAM) has been used as a dry strength agent in the paper industry and other fields.
