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.

Catalyst for epoxide polymerisation and for the copolymerisation of epoxide with carbon dioxide

Described are alkoxylated glycerol acetals according to Formulas (Ia) and (Ib) wherein Rrepresents a linear or branched, saturated or unsaturated and optionally substituted hydrocarbyl residue comprising 6 to 22 carbon atoms and 0 or 1 to 3 double bonds, a benzyl or furfuryl radical, Ris selected from hydrogen, an alkyl, alkenyl or hydroxyalkyl group having 6 to 22 carbon atoms or an acyl group having 6 to 22 carbon atoms and 0 or 1 to 3 double bonds, AO represents an ethylene oxide, a propylene oxide, a butylene oxide unit, or their mixtures, and n is an integer of about 1 to about 100.
