Abstract
A process for preparing dispersions of particles, especially aqueous dispersions is described. The process relates to a dispersion process where a polar solvent is added during the dispersion process such that the hydrogen bonding solubility parameter component, δ, of the initial dispersion mixture increases at least 1.5 units. When the polar solvent added is water the dispersion process is called a Solvent-to-Water Process.
