A process for the manufacture of thermoplastic polymer particles include combining a first solution having a polyetherimide, a polycarbonate, or a combination thereof and an organic solvent with an aqueous solution including a surfactant, and agitating the resulting mixture using a shear force generating device operating at a preselected peripheral rotational speed to provide an emulsion. The emulsion is heated to remove the organic solvent and provide an aqueous polymer dispersion including the thermoplastic polymer particles.

Process for the manufacture of thermoplastic polymer particles, thermoplastic polymer particles prepared thereby, and articles prepared therefrom

A process for the manufacture of polycarbonate particles is disclosed herein. The process includes combining a first solution including a polycarbonate and a phosphorus-containing flame retardant or a flame retardant polycarbonate, and an organic solvent with a second solution including a surfactant and an aqueous solvent substantially immiscible with the organic solvent, under conditions of shear and temperature effective to provide an emulsion. At least a portion of the organic solvent is removed from the emulsion to provide an aqueous slurry having a plurality of particles, wherein the particles include the polycarbonate and the phosphorus-containing flame retardant or the flame retardant polycarbonate.
