Polyether-alcohols

The invention relates to a method for producing polyether alcohols by catalytically attaching ethylene oxide and propylene oxide to H-functional starting substances. Said method is characterized in that at least one multimetal cyanide compound is used as a catalyst, and a block comprised of an alkyl...

Beschreibung
Zusammenfassung:	The invention relates to a method for producing polyether alcohols by catalytically attaching ethylene oxide and propylene oxide to H-functional starting substances. Said method is characterized in that at least one multimetal cyanide compound is used as a catalyst, and a block comprised of an alkylene oxide having at least three carbon atoms in the molecule is attached to the chain end.
