Poly(alkylene oxide) which does not contain any metallic component and does notnleave an odor is prepared simply and efficiently, by a process using a polymerizationninitiator which does not cause any problems in preparing and handling in the preparationnof the polyalkylene oxide by polymerizing an alkylene oxide compound, and does notnrequire special treatment before the initiation of the polymerization. In the process, thenalkylene oxide compound is polymerized in the presence of a phosphine oxide compoundnrepresented by the formula (1):n nwherein Rs are the same or different and each represents a hydrocarbon group having 1nto 10 carbon atoms, and x represents an amount of water molecules contained in termsnof a molar ratio and is within a range from 0 to 5.0. n If desired, the alkylene oxide compound can be polymerized in the presence of saidnphosphine oxide compound and an active hydrogen compound selected from water or an norganic compound having a partial structural formula -OH orn-NH-. |
