METHOD FOR PREPARING METAL CYANIDE CATALYST/POLYOL INITIATOR SLURRIES
Metal cyanide catalyst dispersions in initiator compounds are prepared by precipitating the catalyst in an inert organic compound, mixing the resulting slurry with the initiator and stripping off the inert organic compound. Using this method, an active alkylene oxide polymerization catalyst is prepa...

Zusammenfassung: | Metal cyanide catalyst dispersions in initiator compounds are prepared by precipitating the catalyst in an inert organic compound, mixing the resulting slurry with the initiator and stripping off the inert organic compound. Using this method, an active alkylene oxide polymerization catalyst is prepared. It is not necessary to use a separate organic complexing agent in the preparation. |
