Polyacrylamide - Wikipedia

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

Polyacrylamide Handbook

General description z Standard Emulsions These are dispersions or suspensions of hydrogel (hydrated polymer) of water soluble polymer in a hydrocarbon. They are two-phase heterogeneous systems. The hydrogel is in the shape of microbeads of 1 micron average diameter, it can be considered as a soft solid, their consistency is similar to rubber.

isolation and characterization of polyacrylamide-degrading

Isolation and Characterization of Polyacrylamide-Degrading

Polyacrylamide (PAM) is a water-soluble polymer that is usually produced through the polymerization of acrylamide with one or more copolymers. The amide groups of PAM form hydrogen bonds in aqueous solutions, and high-molecular-weight PAM is an effective flocculant of suspended solids in water via charge neutralization and interparticle ...

Biodegradation of Polyacrylamide and Its Derivatives

Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed. Biodegradation of PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation. Microorganisms have been shown ...

Synthesis and application of amphoteric starch graft polymer

An amphoteric starch-graft-polyacrylamide (S-g-PAM) was prepared by inverse emulsion polymerization, subsequent hydrolysis reaction and Mannich reaction. The copolymerization was carried out using ammonium persulfate and urea as redox initiator. The reaction conditions and application as flocculant were investigated.
