| Zusammenfassung: | This invention relates to processes for preparing poly(oxyethylene) polymers and to methods for preparing same.
Ethoxylations of various initiator compounds are performed in the presence of metal cyanide catalysts. The catalysts surprisingly form a wide variety of polyether products that in most cases contain only small amounts of high molecular weight poly(ethylene oxide). |
