Anionic PAM | High Atomic Weight Polymers | ChemEqual
Anionic Polyacrylamide (PAM) is a substance applied to aggravated soils to diminish erosion and enhance settling of suspended sediments, when used with soiling mulches. Anionic PAM when utilized as a part of horticulture comprises of high atomic weight polymers (12-15 megagrams for each mole) containing >150,000 Acrylamide monomer units..
Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.
