Abstract: A process for the preparation of polyetherpolyols by reacting diols or polyols with ethylene oxide, propylene oxide, butylene oxide or a mixture thereof in the presence of a multimetal cyanide complex catalyst is proposed, the reaction being carried out in a stirred kettle reactor and the reaction mixture being circulated via an external heat exchanger by means of a pump.

Abstract: The invention relates to a method for the production of polyether alcohols by 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 process for preparing polyether alcohols by catalytic addition of alkylene oxides onto a starter substance mixture comprising water-soluble H-functional starter substances which are solid at room temperature, alcohols which are liquid at the reaction temperature and water using alkali metal hydroxides and/or alkaline earth metal hydroxides as catalysts, wherein the amount of water is from 1.0 to 6.0% by weight, based on the weight of the starter substance mixture, and the starter substance mixture comprises no amine constituents.

Abstract: A process for the production of flexible polyurethane foam comprises reacting: (a) optionally modified polyisocyanates with: (b) compounds with reactive hydrogens, and (c) optionally chain extenders and/or crosslinkers, in presence of: (d) blowing agents, (e) catalysts, (f) fire retardants, and optionally: (g) other additives etc. At least 10 wt% of the compounds used in this process comprises polyether-polyols obtained by base-catalysed reaction of lower alkylene oxides with hydroxy-functional starters and subjected, during or after alkylene oxides-addition and with a water content of not more than 0.1 wt.%, to distillation at temperatures above 49 degrees C.
