a factor of 2–3. This applies to both the anionic and non-ionic polyacrylamides, but residual levels from cationic polyacrylamides may be higher. Acrylamide was detected at levels of <5 µg/l in both river water and tap water in an area where polyacrylamides were used in the treatment of potable water. Samples

ANIONIC POLYACRYLAMIDE - Santos
Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

Anionic polyacrylamide hse/anpam/dm/9807-1 Environmental fate A. Bioaccumulation Anionic polyacrylamide being totally soluble in water and insoluble in solvents has a very low octanol/water partition coefficient (P ow), and for all practical purposes : log Pow = 0 Thus, the potential for anionic polyacrylamide to bioaccumulate is zero.

Polyacrylamide CAS#: 9003-05-8 - ChemicalBook
Polyacrylamide is insoluble in benzene, toluene, xylene, gasoline, kerosene, diesel fuel, but soluble in water. Polyacrylamide can react with alkaline with partial hydrolysis of polyacrylamide. It will have imidization reaction in strongly acidic (pH≤2.5) which will reduce its solubility in water.
