Abstract: A method for preparing a polyether polyol in a continuous reaction cycle is described. In the method, a low molecular-weight alcohol is polymerized with an alkylene oxide to obtain a low molecular-weight polymer. The low molecular-weight polymer is used as an initiator to react with the alkylene oxide and the low molecular-weight alcohol in the presence of a DMC catalyst and an acid promoter to obtain an intermediate-target polymer. A portion of the intermediate-target polymer is used for producing the target polymer, and the other portion is recycled for reproduction of the intermediate-target polymer. No initiator prepared with a base catalyst is used, and thus the loss of material and the discharge of residue and waste water are reduced. The DMC concentration is kept constant in the target polymer during the production such that the dewatering time and induction time are greatly reduced.
