摘要： A process to produce a dispersion comprising feeding ethylcellulose polymer and a dispersant into a melt and mix zone of an extruder wherein the ethylcellulose polymer and dispersant are melted and mixed together to form a melt; conveying the melt to an emulsification zone of the extruder in which the temperature and pressure are controlled; feeding a base and water into the emulsification zone wherein the melt is dispersed to form a high internal phase emulsion; conveying the emulsion to a dilution and cooling zone of the extruder; and feeding water into the dilution and cooling zone to dilute the high internal phase emulsion thereby forming an aqueous dispersion is provided.
