Abstract

To provide a polyalkylene oxide composition that has reduced volatile aldehydes and malodors, a high molecular weight, a low level of unsaturation, a narrow molecular weight distribution, and transparency, and contains aluminum, so that it can be highly densified upon conversion into a polyurethane-forming composition; and a method for producing the same.SOLUTION: The present invention relates to: a polyalkylene oxide composition that includes a divalent phosphazenium salt with a specific structure, aluminum, and polyalkylene oxide; and a method for producing the same.SELECTED DRAWING: None
