摘要: The present invention is a method of manufacturing polymer particles. The method includes providing an oil in water emulsion, wherein the oil phase comprises a volatile solvent and at least one water insoluble polymer. The volatile solvent has a solubility of not more than 10% in water and the water insoluble polymer has a weight average molecular weight of at least 2000. The water insoluble polymer is soluble in the volatile solvent. The emulsion is supplied to a rotating surface of a rotating surface reactor. The temperature of the rotating surface is maintained at the boiling point of said solvent or greater. The rotating surface of the reactor spins at a speed sufficient to cause the emulsion to spread over the rotating surface as a continuously flowing thin film wherein a vapor phase containing the volatile solvent is removed. The water insoluble polymer particles are then collected as a slurry of polymer particles and water.
