Abstract
Fine polymer particles are prepared by dissolving a polycarbonate, a poly(arylene ether), or a poly(arylene ether sulfone), each in a specific solvent, to form a slurry, heating the slurry to a temperature greater than the solvent boiling point to form a homogeneous solution, cooling the solution to form a dispersion of fine particles, and isolating the fine particles. A volume-based distribution of the isolated fine particles has a median equivalent spherical diameter less than or equal to 125 micrometers.
