The Micromorphology of Anionic Polyacrylamide Dispersions
Anionic polyacrylamide dispersions were prepared by dispersion polymerization in aqueous salt solutions. The effects of reaction conditions, such as salt concentration, molecular weight of stabilizers, on the micromorphology of the dispersions were investigated systematically by using biological photomicroscope.

What Is Polyacrylamide Used For in Water Treatment?
Polyacrylamide, or PAM, is a water-soluble polymer with excellent flocculation, adsorption, and dispersion properties, commonly sold in powder and emulsion form. In the process of water treatment, PAM can rapidly adsorb suspended particles in water and aggregate into larger particles, which can be removed by precipitation, filtration and other processes to achieve water purification.
