Experiments on stabilized agitated dispersion of non-reacting styrene monomers were conducted at various dispersed phase hold-up fractions, impeller geometries, impeller speeds and agitation times. The experimental drop size distributions obtained were described best by the cumulative upper limit volume, upper limit number and the Nukiyama-Tanasawa ones. Plots of the maximum diameter and the mean diameter vs. the Sauter mean diameter gave straight lines with slopes 1.74 and 0.87, respectively.
