| titleOfInvention | Method for producing medium-molecular-weight polyalkyleneoxide |
| abstract | Provided is a method for producing medium-molecular-weight polyalkyleneoxide having a viscosity-average molecular weight of 100,000 to 2,500,000, by subjecting polyalkyleneoxide having a viscosity-average molecular weight of 3,000,000 or more to heat treatment at 30 to 70ºC in an aliphatic hydrocarbon solvent having a dissolved oxygen concentration of 0.5 mg/L or more, in the presence of 0.001 to 1 parts by mass of a radical generator with respect to 100 parts by mass of the polyalkyleneoxide, and thereafter adding 0.001 to 5 parts by mass of an antioxidant with respect to 100 parts by mass of the polyalkyleneoxide thereby removing the solvent. According to the method of the present invention, medium-molecular-weight polyalkyleneoxide having a viscosity-average molecular weight of 100,000 to 2,500,000 which has excellent storage stability can be industrially obtained without carrying out a γ-irradiation treatment. |
