Polymer particle producing device, polymer particle producing method, program, and storage medium

Abstract

A polymer particle producing device for producing polymer particles by mixing an aqueous phase, a surfactant, and a monomer phase to prepare an oil-in-water emulsion and performing a monomer polymerization reaction using the prepared oil-in-water emulsion is provided. The device includes a supply unit including a flow path for supplying a first aqueous phase and a plurality of flow paths for supplying a surfactant, a monomer phase, and an initiator; a mixing unit disposed on a downstream side of the supply unit and including a first mixer that merges the first aqueous phase, the surfactant, and the monomer phase to prepare an emulsion and transfers the emulsion to a downstream side of the first mixer, and a second mixer that merges the emulsion and the initiator to generate a polymerization liquid and transfers the polymerization liquid to a downstream side of the second mixer; a reaction unit that is disposed on a downstream side of the mixing unit and causes a monomer polymerization reaction using the polymerization liquid; and a flow path for supplying a second aqueous phase to the reaction unit.
