Beschreibung
Zusammenfassung:	A method for continuously producing an aromatic polyether according to the present invention includes simultaneously implementing: a supply step of supplying a polymerization solvent, an alkali metal compound, and a raw material; a polymerizing step; and a movement step. The alkali metal compound is supplied as an aqueous mixture. According to the present invention, clogging of piping in the continuous production apparatus can be suppressed, and the aromatic polyether can be stably obtained.
