Abstract: In a process for preparing polyether alcohols by catalytic addition of at least two alkylene oxides onto H-functional initiator substances, at least one multimetal cyanide compound is used as catalyst and the addition of the alkylene oxides onto the initiator substance includes incorporation of at least one oxyalkylene block during whose formation at least two alkylene oxides are metered in together and the ratio of the alkylene oxides to one another in the mixture is changed during the joint introduction.

Abstract: The invention relates to a method for producing polyether alcohols by the catalytic reaction of H functional compounds with alkylene oxides, whereby a t least one multi-metal cyanide compound is used as the catalyst. The method i s characterised in that the total content of alkaline and acidic impurities contained in the starting material and the alkylene oxides, which reduce the activity of the catalyst, is less than 100 ppm.

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.

Abstract: Production of polyetherols by catalytic adduction of alkylene oxides to initiator substances is such that (i) a tertiary amine catalyst and (ii) a basic alkali(ne earth)- based catalyst are used at 0.1-5% and 0.01-0.25% respectively, each amount based on the polyetherol weight, the weight ratio (i) : (ii) being 1 : 0.002-2.5. An independent claim is also included for polyetherols thus obtained and having a hydroxy number of 80-800 mg KOH/g and a functionality >=2.
