Summary: | PROBLEM TO BE SOLVED: To provide a simple manufacturing process for manufacturing porous nanoparticles.SOLUTION: The process for manufacturing porous nanoparticles includes feeding a dry-blended mixture of at least one resin and a neutralizing agent into a feed section of a screw extruder, injecting a surfactant solution downstream of the hopper, and directly adding an aqueous composition both after the injection of the surfactant solution as well as further downstream. Porous nanoparticles having particle sizes from about 50 nm to about 2 μm and pore diameters from about 20 nm to about 400 nm are continuously recovered from the extruder following this process. |
