METHOD FOR PREPARING METAL CYANIDE CATALYST/POLYOL INITIATORSLURRIES

Metal cyanide catalyst dispersions in initiator compounds are prepared by precipitating the catalyst in an inert organic compound, mixing the resultin g slurry with the initiator and stripping off the inert organic compound. Usin g this method, an active alkylene oxide polymerization catalyst is pre...

Zusammenfassung:	Metal cyanide catalyst dispersions in initiator compounds are prepared by precipitating the catalyst in an inert organic compound, mixing the resultin g slurry with the initiator and stripping off the inert organic compound. Usin g this method, an active alkylene oxide polymerization catalyst is prepared, a nd the preparation method is greatly simplified. Further, it is not necessary t o use a separate organic complexing agent in the preparation.
