Polyacrylamide | 9003-05-8
Polyacrylamide, also briefly referred as PAM, is commonly a polymer with acrylamide monomers bonded connected by end to end configuration; it is a hard glassy solid at room temperature. Because of the difference in production methods, the products can be white powder, translucent beads and flaky like.
Using Polyacrylamide (PAM) to Reduce Erosion on Construction
PAM also may reduce the turbidity of the runoff water beyond the reductions provided by the ground cover. In either case, the steeper the slope, the less benefit PAM will provide and the more critical it is that a good ground cover be used prevent erosion. Higher PAM rates will also be needed on steeper slopes . Dry granules have been applied ...

Dewatered polyacrylamide emulsions differs from standard by the fact that they contain less than 6% water, with the result that the hydrogel has become almost the dry polymer itself. The consistency of the polymer is similar to plastic material. Most dewatered polyacrylamide emulsions from SNF have names starting by DW.

What is Polyacrylamide|PAM FAQ
Polyacrylamide Knowledge . 1. What is polyacrylamide PAM? Polyacrylamide is a polymer (-CH2CHCONH2-) formed from acrylamide subunits, it is long-chain polymer (same molecule repeating itself many times) designed to attract either positively charged particles (organic materials, such as carbon or human waste) or negatively charged particles (inert materials, such as sand or clay).
Polyacrylamide - Wikipedia
Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.

Sodicity is a measure of sodium ions in soil or water relative to calcium and magnesium ions. It is expressed either as sodium adsorption ratio (SAR) or as exchangeable sodium percentage (ESP). If the SAR of the soil equals or is greater than 13 (mmoles L−1)0.5 or ESP equals or is greater than 15, the soil is termed sodic (Richards 1954).
