Polyacrylamide - Wikipedia

Polyacrylamide (abbreviated as PAM) 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

1. General description 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.

Sep 7, 2018 · The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1, 9,...

NICNAS has assessed anionic polyacrylamide in an IMAP Tier 1 assessment and considers it a polymer of low concern1. In addition, based on an assessment of environmental hazards, NICNAS also identified anionic polyacrylamide as a chemical of low concern to the environment (NICNAS, 2017).
