Beschreibung
Zusammenfassung:	The present invention relates to a production method of polyalkylene oxide particles including a step of forming the polyalkylene oxide particles by polymerization of an alkylene oxide in a polymerization solution containing a polymerization solvent and a catalyst dispersed in the polymerization solvent. The average particle diameter of the catalyst is more than 25 µm.
