    Abstract: Rigid polyurethane foam is produced from mixtures of (b1) polyfunctional polyether-ols with OH numbers of 40-800 (including at least one with OH no. above 150) and more than 30 wt% ethylene oxide based on total alkylene oxide and (b2) polyether-ols with OH nos. above 40 based mainly on propylene- and/or butylene oxide, using PIR catalysts and an index of 80-500. A method for the production of rigid polyurethane foam with urethane and mainly isocyanurate groups by reacting (a) optionally modified polyisocyanates with (b) a polyol mixture and optionally (c) other compounds with isocyanate-reactive hydrogen atoms, in presence of (d) water, (e) catalysts, (f) fire retardants, (g) blowing agents and optionally (f) other additives etc. The polyol mixture (b) comprises (b1) di- to octa-functional polyether-ol(s) based on ethylene oxide (EO) and optionally propylene oxide (PO) and/or butylene oxide (BO), with an EO content of more than 30 wt% based on total alkylene oxide and an OH number of 40-800 mg KOH/g (including at least one polyether-ol (b1.1) with an OH number of more than 150), and (b2) polyether-ol(s) with an OH number of more than 40, based on PO and/or BO and optionally EO, and the foam is produced with a characteristic index of 80-500 in presence of PIR catalysts.. An Independent claim is also included for rigid polyurethane foam as above obtained by this method.

    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.
