A process is disclosed which eliminates the necessity of applying a mold release agent to the mold when producing integral skinned polyurethane foam moldings in closed molds. This is accomplished by incorporating in the foamable reaction mixture an additive, which imparts mold release properties, said additive containing at least 25 aliphatic carbon atoms and being the salt of an aliphatic carboxylic acid and either a primary amine or an amine which contains either amide or ester groups. |
