METHOD FOR PRODUCING DMC CATALYSTS.

摘要

The invention relates to an improved method for producing double metal cyanide (DMC) catalysts for use in the production of polyether polyols by polyadditon of alkylene oxides to active hydrogen atom comprising starter compounds. The DMC catalyst dispersion is produced using a mixing nozzle, preferably a jet disperser. The DMC catalysts obtained by the inventive method and used for the production of polyols have an increased activity, a reduced particle size and a denser particle size distribution.
