    • PURPOSE: Double-metal cyanide(DMC) catalysts which can be used to prepare polyols, a process for preparing DMC catalysts, a process for polymerizing an alkylene oxide in the presence of a DMC catalyst prepared according to the process are provided. CONSTITUTION: The double-metal cyanide catalyst is characterized in that it is prepared by combining at least one metal salt, at least one metal cyanide salt, at least one organic complexing ligand, at least one alkali metal salt, and optionally, at least one functionalized polymer, under conditions sufficient to form a catalyst; and adding the at least one alkali metal salt to the catalyst so formed in an amount such that the catalyst includes the at least one alkali metal salt in an amount of from about 0.4 to about 6 wt.% based on the total weight of the catalyst. The process for preparing a double-metal cyanide catalyst comprises the steps of combining at least one metal salt, at least one metal cyanide salt, at least one organic complexing ligand, at least one alkali metal salt, and optionally and at least one functionalized polymer under conditions sufficient to form a catalyst; and adding at least one alkali metal salt to the catalyst so formed in an amount such that the catalyst includes the at least one alkali metal salt in an amount of from about 0.4 to about 6 wt.% based on the total weight of the catalyst.
