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

Polyacrylamides are produced by the polymerization of acrylamide (C 3 H 5 NO), a compound obtained by the hydration of acrylonitrile. Acrylamide is usually dissolved in water; it has toxic effects on the nervous system and must be handled under special protective procedures.

Polyacrylamide degradation and its implications in - Nature

What is Polyacrylamide (PAM)? Polyacrylamide is a synthetic water-soluble polymer made from monomers of acrylamide. PAM binds soil particles together. Once soil particles suspended in water are bound together by PAM, they settle out, so water has a harder time washing them out of the field.
