is polymer a acrylamide
Acrylamide is the building block for the polymer, polyacrylamide, which is considered a non-toxic additive. However, polyacrylamide may be contaminated with its toxic building block, acrylamide. To date there have been improvements in the polymerization process reducing the monomer content of these polymers from 5% to 0.3%. In addition, regulations have been set on the amount of acrylamide that is present in polyacrylamide. For example, a limit of 500ppm in polyacrylamide preparations (PAM) is used in agriculture or water treatment. Unfortunately, PAM hydrogels degrade releasing acrylamide and other toxic substances to the environment.
