Anionic Polyacrylamide Polymers Effect on Rheological

Polyacrylamide (PAM) is a long‐chain synthetic polymer that acts as a strengthening agent, binding clay particles together. The interaction between anionic PAM and clay particles is not well understood yet. This interaction was evaluated by rheological measurements for Na‐montmorillonite suspensions.

Findings on the influence of molecular size (chain length) on toxicity in aquatic organisms vary between studies. While Bolto and Gregory (2007) describe APAM with a long chain length as most toxic, other studies could not establish a direct correlation between chain length and toxicity (Beim and Beim, 1994; Hall and Mirenda, 1991).

The polymer can be synthesized as a simple linear chain or as a cross-linked structure. PAM increases the viscosity of water and encourages the flocculation of particles present in water. The cross-linked polymer can absorb and retain extemely large amounts of water because the amide groups form strong hydrogen bonds with water molecules.
