摘要： In a process for producing polyoxymethylene-polyalkylene oxide block copolymers comprising the step of polymerizing an alkylene oxide in the presence of an OH-terminated polyoxymethylene polymer and a catalyst, the polyoxymethylene polymer has a number-average molecular weight Mn determined after derivatization with propylene oxide and gel permeation chromatography against polystyrene standards with tetrahydrofuran as the eluent of ≥1100 g/mol to ≤2300 g/mol and the ratio of alkylene oxide to polyoxymethylene polymer is ≥0.05 mol/g. The invention further relates to copolymers obtainable by the process, to a process for producing polyurethane polymers using these copolymers and to polyurethanes obtainable therefrom.

摘要： A method for producing polyether ester carbonate polyols by catalytically adding alkylene oxide and carbon dioxide to an H-functional initiator substance in the presence of a double metal cyanide catalyst. The method comprises the following steps: (α) feeding a partial amount of H-functional initiator substance and/or a suspension agent which does not have any H-functional groups into a reactor, optionally together with DMC catalyst, (γ) adding alkylene oxide and optionally carbon dioxide to the reactor during the reaction. The method is characterized in that in step (γ) lactide is added to the reactor.
