Beschreibung
Zusammenfassung:	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. L'invention concerne un procédé de fabrication de particules de polycarbonate. Le procédé comprend la combinaison d'une première solution comprenant un polycarbonate et un ignifugeant contenant du phosphore ou un polycarbonate ignifuge et un solvant organique, avec une seconde solution comprenant un tensioactif et un solvant aqueux sensiblement non miscible au solvant organique, dans des conditions de cisaillement et de température efficaces pour former une émulsion. Au moins une partie du solvant organique est retirée de l'émulsion pour former une suspension aqueuse comprenant une pluralité de particules, les particules comprenant le polycarbonate et l'ignifugeant contenant du phosphore ou le polycarbonate ignifuge.
