Method for continuously producing aromatic polyether

A method for continuously producing an aromatic polyether by simultaneously implementing

• a supply step of supplying a polymerization solvent, an alkali metal compound, and a raw material into a continuous production apparatus in which a plurality of reaction vessels are sequentially connected,
• a polymerizing step of forming a reaction mixture by carrying out a polymerization reaction in the polymerization solvent in at least one or more of the reaction vessels, and
• a movement step of sequentially moving the reaction mixture to each reaction vessel,
• wherein the alkali metal compound is an aqueous mixture and is supplied into the continuous production apparatus separately from a mixture comprising at least part of the raw material and the polymerization solvent.
