  • Patent number: 9458286
    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.
    Type: Grant

  • Patent number: 8901165
    Abstract: Described are alkoxylated glycerol acetals according to Formulas (Ia) and (Ib) wherein R1 represents 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, R2 is 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.
