Abstract: The present invention relates to methods for the alkylene oxide-free preparation of compositions comprising polyetherols using one or more alkylene carbonates as reactants. The polyetherol compositions prepared according to the invention ideally do not comprise carbonate or comprise almost no carbonate. The present invention also comprises the use of alkylene carbonate for preparing polyetherols or compositions comprising polyetherols and polyetherols or compositions comprising polyetherols prepared by the method according to the invention.
