Abstract: Described herein are processes for producing a polyurethane foam by mixing the following: (a) polymeric MDI with less than 40% by weight content of difunctional MDI and an aliphatic halogenated hydrocarbon compound (d1) composed of 2 to 5 carbon atoms and of at least one hydrogen atom and of at least one fluorine and/or chlorine atom, where the compound (d1) includes at least one carbon-carbon double bond, to give an isocyanate component (A), and reacting with a polyol component (b) to give the polyurethane foam. Also described herein is a polyurethane foam obtainable by said process.
