Abstract:
The invention relates to a catalyst for catalysing the polymerisation of epoxides, and which is to be improved such that it allows a more efficient reaction to be carried out. This is achieved by providing a catalyst obtainable by mixing a) at least one double metal cyanide compound, b) at least one organic complexing agent, and c) at least one primary alcohol with 6 to 24 C atoms. In addition, the invention relates to a method for the polymerisation of epoxides, and to the use of the claimed catalyst for the polymerisation of epoxides and the copolymerisation of epoxides with carbon dioxide.
