Abstract
A homogeneous, demixing-stable polyol component comprising at least two relatively high molecular weight compounds containing at least two reactive hydrogen atoms and, if desired, low molecular weight chain extenders and/or crosslinkers and also, if desired, blowing agents, catalysts and further auxiliaries and/or additives is prepared by adding at least one amine and at least one organic and/or modified organic isocyanate to this component. This polyol component is useful for producing polyurethanes, in particular compact and foamed polyurethanes.
