摘要： Stable aqueous dispersions or emulsions can be prepared by merging into a mechanical dispenser a stream of a molten or liquid disperse phase with a stream of a molten or liquid continuous phase to form a dispersion or emulsion. The molten or liquid disperse phase stream contains a polymer that is preferably a solid at room temperature, but molten at some advanced temperature. The polymer is formed in a molten state or formed and melted by a continuous reaction process such as an extrusion process, including melt extrusion or compound extrusion. It has been discovered that low polydisperse submicron sized dispersion can be prepared by the method of the present invention.
