Abstract: The invention relates to a method for the production of polyether alcohols b y catalytic addition of at least two alkylene oxides to H-functional starting materials. Said method is characterised in that at least one multi-metal cyanide compound is used as catalyst and in the course of the addition to the starting material at least one oxyalykylene unit is incorporated, during which a common dosing of at least two alkylene oxides occurs, whereby during said common dosing the ratio of the amounts of alkylene oxides to each other is varied.

Abstract: The invention relates to a method for producing polyether alcohols by means of catalytic polymerisation of alkylene oxides. Said method is characterised in that the alkylene oxide contains propylene oxide, at least one multimetal cyanide compound is used as a catalyst, and the free alkylene oxide content in the reactor is lower than or equal to 8 wt. %, in relation to the total amount of educts and reaction products in the reactor.

Abstract: The invention relates to a method for producing polyetherpolyols by reacting diols or polyols with ethylene oxide, propylene oxide, butylene oxide or mixtures thereof in the presence of a multi-metal cyanide complex catalyst. The reaction is performed in stirred-tank reactor and the reaction mixture i s circulated via an externally located heat exchanger, using a pump.

Abstract: Polyetherols based on solid initiator substances and liquid, hydroxyl-containing coinitiators are prepared by a catalyzed addition reaction of alkylene oxides by a process in which the initiator combination contains ethoxy structures, the ratio of the average number of hydroxyl groups per mole of initiator combination to the number of ethoxy structures in the polyetherol being from 1:0.2 to 1:1.8 and the ratio of the amounts by weight of the ethoxy structures to the average molecular weight of_the polyetherol being from 1:2 to 1:15. The polyetherols prepared by this process are used for the preparation of PUR, in particular rigid PUR foams.
