Abstract

Non-Newtonian fluids, such as partially polymerized monomers or solutions of polymer in monomer may be pressure atomized below the free surface of a continuous liquid phase to produce a dispersed phase. A uniform or customized droplet size distribution can be obtained by imposing a required pressure pulsation on a flowing monomer upstream the atomizer inlet. This initial particle size distribution can be maintained or modified during subsequent polymerization process in a low shear, controlled turbulence flow pattern, created without mechanical agitation within the continuous liquid, by continuously or periodically injecting an inert gas at selected locations within the reactor.
