Abstract (en)

[origin: WO2011107366A1] The invention relates to a method for producing polyurethanes by reacting a) polyisocyanates with b) compounds having at least two hydrogen atoms reactive with two isocyanate groups, characterized in that at least one polyether alcohol b1) having a functionality of 2-8 and a hydroxyl number of 200-600 mg KOH/g is used as the compounds having at least two hydrogen atoms reactive with two isocyanate groups, said alcohol having been produced by building up alkylene oxides b1b) on compounds having at least two hydrogen atoms reactive with alkylene oxides using an amine b1c) as a catalyst.
