In the storage method, the synthesized double metal cyanide complex catalyst is stored at a weight ratio of 0.01 to 1000 in the organic ligand used for the synthesis or other organic ligands, preferably at a weight ratio of 0.1 or more. It is intended to provide a storage method and a storage method in which a monoepoxide subjected to a ring opening reaction using the double metal cyanide complex catalyst is stored at a weight ratio of 0.01 to 1000, preferably 0.1 or more. As the organic ligand, one or more selected from ether, ester, alcohol, aldehyde, ketone, amide, nitrile, and sulfide is used.

られた。In the present invention, the mechanism of ring-opening polymerization of the monoepoxide of the double metal cyanide complex catalyst is not always clear, but the coordination state of the organic ligand of the double metal cyanide has a great influence on the catalytic activity. It is considered something. Therefore, it is considered that the preservation while being brought into contact with the organic ligand led to a good result with respect to the reaction induction time and the reaction rate. Furthermore, in the present invention, it was confirmed that the reaction time was shorter than the value immediately after the synthesis of the double metal cyanide complex catalyst, and that the reaction rate was also improved.
