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 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 th e starting material at least one oxyalykylene unit is incorporated, during whi ch 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 polyester-polyether block copolymers which can be produced by the catalytically induced attachment of alkylene oxides to H functional starting materials. Said copolymers are characterised in that polyester alcohols are used as the H functional starting materials and multi-metal cyanide compounds are used as the catalysts.

Abstract: A polyether-ol (PEOL) mixture for the production of flexible polyurethane foam comprises (b1) 2- to 8-functional PEOL with more than 50% prim. OH groups based on propylene and/or butylene oxide (PO/BO) and ethylene oxide (EO), (b2) 2- to 6-functional PEOL based on PO and/or BO and (b3) other PEOL with more than 25% prim. OH groups, based on EO and PO. A process for the production of sound-damping and energy-absorbing flexible polyurethane (PUR) foam by reacting: (a) optionally modified polyisocyanates; with (b) a polyether-ol mixture; and optionally (c) other compounds with isocyanate-reactive hydrogen atoms; in presence of (d) water and/or other blowing agents; (e) catalysts; and optionally (f) other additives, etc.. Component (b) comprises (b1) di- to octa-functional polyether-ol(s) based on a mixture of PO and/or BO and more than 40 wt.% EO, with an OH number of 20-1000 mg KOH/g and a primary OH group content of more than 50%, with the proviso that (b1) contains at least one at least difunctional polyether-ol (b1.1) with an OH number of 20-100, (b2) di- to hexa-functional polyether-ol(s) with an OH number of more than 30, based on PO and/or BO, and (b3) other polyether-ol(s) based on EO and PO with a prim. OH group content of more than 25%, with the proviso that the content of (b1) in (b) is more than 30 wt%. An Independent claim is also included for PUR foam obtained by this process.
