METHOD FOR PRODUCING POLYSTYRENE MICROPARTICLES BY USING A SUPERCRITICAL ANTI-SOLVENT

摘要

A method for producing polystyrene microparticles using a supercritical anti-solvent, including preparing a solution, heating it, compressing it, passing it through a nozzle, mixing with a supercritical anti-solvent, precipitating polystyrene particles and collecting them, characterized in that the collection of polystyrene particles is carried out into a liquid trap, while the mixing process with a supercritical anti-solvent is carried out at P = (1.1-3) Pcr and temperature T = (1-1.1) Tcr.
