Abstract: The present invention relates to a process for producing polyurethane moldings, wherein (a) organic polyisocyanates are mixed with (b) one or more compounds having at least two hydrogen atoms which are reactive toward isocyanate, comprising polyester polyol, (c) blowing agent, (d) catalyst, and (e) propylene carbonate and compounds selected from the group consisting of at least one compound of the general formula (I) and a compound of the formula (II), to give a reaction mixture, introduced into a mold and allowed to react to give a polyurethane molding. The present invention further relates to polyurethane moldings obtainable by such a process and also the use of these moldings as steering wheels, seats, armrests and in particular as shoe soles.
