Abstract
Non-Newtonian fluids, such as partially polymerized monomers or solutions of polymer in monomer may be pressure atomized below the surface of an immiscible continuous liquid phase to produce a dispersed phase having a uniform particle size distribution. A dual or customized size distribution can be obtained by imposing a controlled pressure pulsation on a flowing fluid upstream the atomizer inlet. Such dispersion may be further polymerized to produce a uniform or customized bead size product.
