Zusammenfassung: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.
