Abstract: A method for the production of polyurethanes (I) by reacting (a) polyisocyanates with (b) compounds with at least 2 NCO-reactive hydrogen atoms, in which (b) contains at least one compound (bi) with at least 2 NCO-reactive hydrogens and at least one urethane group, obtained by reacting (bi1) compounds with at least 2 amino groups with (bi2) compounds with hydroxyl groups and (bi3) urea, or by reacting non-functional urethanes with (bi4) compounds containing hydroxyl groups.
