The Micromorphology of Anionic Polyacrylamide Dispersions

Abstract:

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. The results showed that the particle shape in stable dispersions were more regular, basically spherical or ellipsoidal. Stable anionic polyacrylamide dispersions could be obtained on condition that salt concentration was between 26%~30%, molecular weight of stabilizers between 1.760×10⁶~2.317×10⁶ g•mol^-1.
