Polymer - solvent interaction effect on the dispersability of alumina particles

الملخص EN

The dispersion stability was discussed for alumina particles in solutions of different alkyl methacrylates (methyl, n-butyl and 2-ethylhexyl) / meth acrylic acid copolymers.

It was found that the molecular structure of the attached dispersant was important in affecting the packing density, and the marked differences between the packing density from various organic solvent was explained in terms of Flory-Huggins parameter, which is related to the solubility parameter of the solvent.
