Process for producing molded polyurethane parts using as internal release agents, compounds of the general formula ##STR1## in amounts of 0.5 to 10 weight percent, based on the reaction formulation, in which at least one R.sup.2 radical in the average molecule represents ##STR2## R.sup.3 is a divalent hydrocarbon radical with 2 to 4 carbon atoms and R.sup.4, R.sup.5 are univalent hydrocarbon radicals or together are part of a morpholine or a piperazine ring. The molded polyurethane parts can be removed from the mold using significantly lower tensional forces without residues being built up on the mold.
