PURPOSE: A method for manufacturing a polyether is provided to improve reaction efficiency and the yield of polyether using a reactor equipped with a heat exchanger and a high shear inline mixer in polyether polymerization. CONSTITUTION: A method for manufacturing a polyether comprises the steps of: (S101) adding raw materials to a nitrogen-substituted reactor; (S103) mixing the raw material in the mixer included within the reactor; (S105) removing water within the reactor by a vacuum pump; (S107) injecting alkylene oxide into a reactor and initiating ring-opening reaction of a reactant; (S109) stirring the reactant within the reactor in which the alkylene oxide is input; (S111) removing a monomer contained within the reactant; and (S113) filtering the reactant from which monomer is removed. |
