Abstract: Polyurethanes are prepared by reaction of: (a) at least one polyisocyanate with (b) at least two compounds having at least two hydrogen atoms reactive to isocyanates, by insertion of the liquid starting components into a mold on the surface of a building component, and finally insertion of the building component with the starting components into a closed mold. The compounds with at least two hydrogen atoms reactive to isocyanate groups are selected from 1-5C, preferably 2C dialkyltoluylenediamines in the alkylene chain and 2,2'-dimethyl-4,4'-methylene bis(cyclohexylamine). An Independent claim is included for a polyurethane prepared as above.
