    Abstract: Preparation of polyurethane-foaming substance (A) with reduced emission comprises: reacting polyisocyante with a compound (B) containing at least two reactive hydrogen atoms of isocyanates in the presence of a catalysts, where the catalyst is at least an alcohol compound (I). Preparation of polyurethane-foaming substance (A) with reduced emission comprises: reacting polyisocyanate with a compound containing at least two reactive hydrogen atoms of isocyanates in the presence of a catalyst, where the catalyst is an alcohol compound of formula (I). R1, R2 : -C aH 2a+1 or -C bH cN d; a : 1-4; b : 3-7; c : 6-14; d : 0-2; R3 : C eH fO g; e : 0-4; f : 0-8; g : 0-2; R4 : H, CH 3 or C 2H 5; and n, m : 1-5. An independent claim is also included for the polyurethane-foaming substance obtained by the method with a content of volatile organic compounds (less than 100 ppm) and condensable compounds (less than 250 ppm).
