Abstract: A method for the production of polyurethanes (I) for glueing organic building materials, especially natural materials, by reacting (a) polyiso-cyanates with (b) compounds containing isocyanate-reactive hydrogens, in which (b) contains (b1) polyether-alcohol(s) obtained by reacting alkylene oxides with starter substances containing H-functional compounds (II) which are chemically similar to those in the organic building material. Independent claims are included for (1) polyurethanes obtained by this method for processing organic building materials (2) polyurethane adhesives, stoppers and filling compounds obtained by this method .
