Abstract (en)
[origin: DE19809539A1] The invention relates to double metal cyanide catalysts (DMC) which are applied to solid, inert non-foamed supports, introduced into the same or shaped into forms. The invention also relates to the production of said double metal cyanide catalysts and to their use for producing polyether alcohols with a low unsaturated compound content by means of catalytic ring-opening polymerisation of alkylene oxides. The DMC can be e.g., zinc hexacyanocobaltate.
