Cationic polyacrylamide copolymers (PAMs): environmental half

Background Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils. To obtain detailed information on the polymer¡¯s fate in the soil compartment, the degradation of 14C

Polyacrylamide

[1] Copolymers and modified polymers [ edit] Linear polyacrylamide is a water-soluble polymer. Other polar solvents include DMSO and various alcohols. Cross-linking can be introduced using N,N-methylenebisacrylamide. Some crosslinked materials are swellable but not soluble, i.e., they are hydrogels .

spotlight on the life cycle of acrylamide-based polymers

Spotlight on the Life Cycle of Acrylamide-Based Polymers

Polyacrylamide, or PAM, is made from the acrylamide monomer. Although PAMs are not toxic, the starting building block, acrylamide, is one of the substances of very high concern (SVHC) and is included in the candidate list for authorization [ 6, 7, 8 ].
