Zusammenfassung:The method for continuously producing an aromatic polyether concurrently performs a supply step, wherein a polymerization solvent, an alkali metal compound and a starting material are supplied; a polymerization step and a transfer step. The alkali metal compound is supplied in the form of an aqueous mixture. According to the present invention, clogging of a pipe in a continuous production apparatus is suppressed, so that an aromatic polyether is able to be obtained stably. 本发明的芳香族聚醚的连续制造方法同时并行地进行供给聚合溶剂、碱金属化合物以及原料的供给工序;聚合工序以及移动工序。将碱金属化合物以水性混合物的形式供给。根据本发明,能抑制连续制造装置的配管的阻塞,稳定地得到芳香族聚醚。
