    摘要: The invention relates to a method for producing polyurethanes by reacting at least one polyisocyanate with at least one compound having at least two hydrogen atoms that are reactive with isocyanate groups. The method is characterised in that at least one polyether alcohol is used for the connection to at least two active hydrogen atoms. Said polyether alcohol is produced by adding alkylene oxides to H-functional initiator substances by means of multi-metal cyanide catalysis. The reaction is carried out in the presence of at least one metallic salt.

    摘要: The invention relates to a method for the continuous production of polyether alcohols by reacting alkene oxides with H-functional initiation substances in the presence of DMC catalysts. According to said method: a) a preliminary product and a DMC catalyst are first provided in a reactor, b) alkene oxide is added in such a way that the dosing speed, which is maintained for the continuous operation of the reactor, is reached within 100 to 3000 seconds, c) during or after step b) the initiation substance is added in such a way that the dosing speed, which is maintained for the continuous operation of the reactor, is reached within 5 to 500 seconds, d) once the contents of the reactor have reached the desired level for the continuous operation of said reactor, the product is continuously removed. The initiation substance and alkene oxide are added simultaneously in quantities that enable the level of the contents in the reactor to remain constant and the DMC catalyst is added in such a way that the catalyst concentration required for the continuous operation of the reactor is maintained.
