Polyacrylamide

[1] Physicochemical properties [ edit] Polyacrylamide is a polyolefin. It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone.

binding of anionic polyacrylamide with amidase and laccase under 298, 303, and 308 k: docking and molecular dynamics simulation studies combined

Binding of Anionic Polyacrylamide with Amidase and Laccase under 298, 303, and 308 K: Docking and Molecular Dynamics Simulation Studies Combined

Abstract Amidase and laccase play a key role in the degradation process of anionic polyacrylamide (HPAM). However, the largest challenge of HPAM enzymatic degradation is whether the enzyme can bind with a substrate for a period of time.

microbial degradation of polyacrylamide and the deamination product polyacrylate

Microbial degradation of polyacrylamide and the deamination product polyacrylate

Both single microbial species as well as mixed populations have been investigated for degradation. Biodegradation of polyacrylamide begins with amidase catalysed deamination of polyacrylamide to ammonia and polyacrylate. The liberated ammonia is then used as a nitrogen source for growth by the microbes. The carbon backbone, polyacrylate, is
