摘要： A method of manufacturing porous core-shell polymer particles having a nonporous shell including: providing a first organic solvent containing a dissolved polymer; dispersing the organic solvent in an aqueous phase containing a stabilizer to form an emulsion; adding the emulsion to a second organic solvent wherein the second organic solvent is miscible with water and the first organic solvent, and a non-solvent for the polymer; and evaporating the first and second organic solvents from the emulsion to form core-shell polymer particles. The method results in core-shell polymer particles comprising a common binder polymer for the core and the shell wherein the core has a porosity and the shell is non-porous. The particles have a porosity from 10 to 70 percent.
