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.

Abstract: The present invention relates to a process for the production of polyether alcohols by catalytic addition of alkylene oxides to H-functional initiators using amines as catalysts, wherein the addition of the amines to the reaction mixture is effected prior to or at the commencement of the chemical addition of the alkylene oxides and also at least once during the reaction, said additional addition of the catalyst being carried out at the point of the reaction at which there is an increased occurrence of side reactions and/or when the alkylene oxides undergo a change in the polyether chain.
