Acrylamide (AM) is a hydrophilic and nonionic monomer and has high rate constant for polymerization in water.

Water treatment segment accounts for the largest share in the global acrylamide market which is followed by the oil and gas sector.
Geographically, the global acrylamide market is broadly segmented on the basis of seven regions, namely North America, Latin America, the Middle East and Africa, Japan, Asia Pacific, Western Europe and Eastern Europe.
For sand mine operators, the selection and proper use of PAM to minimize residual amounts of monomer acrylamide that are present can impact two of a mining facility's largest process flows.
The Center for Disease Control, Environmental Protection Agency and Pollution Control Agency have all conducted studies showing that, upon exposure to the environment, acrylamide and PAM biodegrade or hydrolyze within hours to days (depending upon microbial concentrations, pH levels and temperature) and are gone before reaching most water sources.
Common cationic polyacrylamides produced industrially Include copolymers of acrylamide (1) with AETAC (6), MAETAC (7), MAPTAC (9), or DADMAC (10) (Figures 7 and 2).
In general, cationic methacrylates and methacrylamides are more reactive than their acrylate and acrylamide counterparts.

The monomer stream (50 wt% aqueous solution of acrylamide
) was injected into barrel section 4 using a water-cooled injection nozzle.
By contrast, recent analytical work suggests that acrylamide
is present naturally in many cooked foods at levels that exceed 1,000 parts per billion and has been present in these foods for a long time.
Kellogg's Special K was found to have up to 300ppb of acrylamide
and Kellogg's Rice Crispies between 110 and 150ppb.
