Disclosed is a double metal cyanide complex catalyst for producing polyol, which is produced by using monovalent alcohol and polyvalent alcohol as a complexing agent. The double metal cyanide complex catalyst has advantages in that when polyol is produced by an epoxide polymerization reaction, the amount of unsaturated polyol produced is small, catalyst activation time is short, and the production yield of polyol is increased, therefore there is no need to remove remaining catalyst from polyol after polymerization reaction. |
