Abstract:
This invention relates to novel double metal cyanide catalysts and to a process for the production of these double metal cyanide catalysts. These DMC catalysts can be used to prepare polyoxyalkylene polyols which have low amounts of high molecular weight tail compared polyoxyalkylene polyols prepared from DMC catalysts of the prior art.
