Polyacrylamide

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.

ANIONIC POLYACRYLAMIDE

Synonyms: Anionic polyacrylamide 3 PHYSICO-CHEMICAL PROPERTIES Polyacrylamide polymers can exist in cationic, anionic or non-ionic forms, depending on their ionic charge. The non-ionic form of polyacrylamide is generated from the basic polymerisation of acrylamide. Anionic polyacrylamide polymer can then be formed from the hydrolysis of the

Using Polyacrylamide (PAM) to Reduce Erosion on Construction

Figure 1. Granular or powdered PAM formulation is used primarily in hydroseeding. Erosion Control The erosion process is initiated when a rain droplet impacts the soil surface and dislodges soil particles. Once overland flow begins during a heavy or prolonged rain, these soil particles are then washed downslope.
