    摘要： The present invention relates to highly active, substantially crystalline double metal cyanide (DMC) catalysts, a process for the preparation of these double metal cyanide catalysts, a process for producing polyether polyols by the polyaddition of alcohol ethers onto starter compounds containing active hydrogen atoms from these DMC catalysts, and to the polyether polyols produced by this process. The DMC catalysts of the invention comprise a) double metal cyanide compounds, b) organic complexing ligands, and c) functionalized polymers. These catalysts exhibit increased activity in the process for the production of polyether polyols.
