METHOD FOR PREPARING METAL CYANIDE CATALYSTS AND FOR USING SAME

摘要

Metal cyanide catalyst dispersions in initiator compounds are prepared by precipitating the catalyst in an aqueous phase, mixing the resulting slurry with the initiator and stripping off the water and other volatiles. Using this method, an active alkylene oxide polymerization catalyst is prepared, and the preparation method is greatly simplified. Further, it is not necessary to use a separate organic complexing agent in the preparation.
