A catalyst for the polymerization of an alkylene oxide compound is composed of a phosphazene compound or a phosphazenium salt which is derived from the phosphazene compound and an active hydrogen compound. A poly(alkylene oxide) can be efficiently produced by polymerizing the alkylene oxide compound in the presence of the catalyst and, when the catalyst is composed of the phosphazene compound, the active hydrogen compound. The poly(alkylene oxide) contains no residual metal components and compared with those produced using conventional amine-base catalysts, has also significantly improved odor.
