anionic poly-acrylamide (apam)

anionic polyacrylamide. composition: negatively charged polymer pam polyacrylamides of polyacrylamide are widely used as retention aids and dry-strength resins. however, different molecular mass ranges are used for these two roles. anionic polyacrylamide polymer pam polyacrylamide retention aids typically have molecular masses in the range of 5 to 20 million grams per mole.

cationic polyacrylamide(pam) for water treatment

cationic polyacrylamide, is a white powder water -soluble polymer which is polymer pam polyacrylamideized by cationic monomer and acrylamide. it has the function of decolorizing, adsorbing, turbid eliminating and bonding. it generate a good flocculation and can decrease the resistance between liquids.

polyacrylamide degradation and polymer polyacrylamide

the molecular weight (mw) of commercial pam ranges from 10 5 to 10 7 da. high mw pam (>10 6 da) has a wider range of applications due to its high viscosity, drag reduction capabilities, and water
