Superabsorbents are produced by polymerization in the presence of at least one unsaturated polyetherol selected from the group consisting of polyetherols having the following structural formulae (1), (2), (3) and (4): 

Method for the production of superabsorbers

The present invention relates to a process for the preparation of at least one alkoxylate comprising the bringing into contact of an alkylene oxide mixture at least comprising ethylene oxide with at least one starter compound in the presence of at least one double-metal cyanide compound, where, during the induction phase, the sum of inert gas partial pressure and ethylene oxide partial pressure is 1.5 bar to 6.0 bar, to the alkoxylates obtainable by such a process, and to the use of such alkoxylates as emulsifier, foam regulator or as wetting agent for hard surfaces.

Method for producing alkoxylated products at optimized reaction pressures

A process for preparing polyether polyols includes a precipitation step, a recrystallization step, and a reaction step. In the precipitation step, a multimetal cyanide compound is precipitated by reaction of a metal salt with a cyanometalate compound. In the recrystallization step, the multimetal cyanide compound precipitated above is recrystallized by adding further metal salt and/or further cyanometalate compound. The recrystallization forms a multimetal cyanide catalyst compound. In the reaction step, an initiator and one or more alkylene oxide are reacted in the presence of the multimetal cyanide catalyst compound.
