ANIONIC POLYACRYLAMIDE - Santos

Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

Best Practices Guidance for the Use of Anionic Polyacrylamide

Anionic vs. Cationic PAM ?Polyacrylamides can be anionic (negatively charged) or cationic (positively charged). ?Fish have a negative charge on their gill mucous. ?Anionic PAMs are repelled by the negative charge on fish gills, while cationic PAMs are attracted to it. ?As a result, the cationic PAM will attach to gills,

DEFINITION Application of water-soluble anionic polyacrylamide (PAM) to the soil. PURPOSE This practice is used to accomplish one or more of the following purposes: Reduce soil erosion by water or wind. Improve soil surface infiltration rate and minimize soil crusting to allow for uniform plant growth. CONDITIONS WHERE PRACTICE APPLIES

Using Polyacrylamide (PAM) to Reduce Erosion on Construction

Abstract. Ultraviolet (UV)-initiated template polymerization (UTP) was used as a feasible strategy to prepare a novel anionic polyacrylamide (APAM) with a microblock structure. In the template copolymerization system, acrylamide (AM) and sodium allylsulfonate (SAS) were used as monomers, and poly (allylammonium chloride) (PAAC) as a template
