ABSTRACT:
A continuous suspension polymerization process for the production of polymeric particles substantially uniform particle size, entailing the steps of forming monomer droplets of substantially uniform particle size through an orifice under vibration, and effecting polymerization of the monomer droplets in an aqueous medium. The process permits carrying out polymerization without destruction or agglomeration of the monomer droplets, so that the particle size of the polymeric particles thus produced depends predominantly upon the particle size of the monomer droplets as initially formed.
