PROCESS FOR THE PREPARATION OF OPTIONALLY CELLULAR POLYURETHANE-POLYUREA MOLDED PARTS USING URETHANE GROUP- AND ISOCYANURATE GROUPCONTAINING 2,4- AND/OR 2,6-TOLUENE DIISOCYANATES The invention relates to a process for the preparation of cellular or non-cellular polyurethanepolyurea molded articles. The new process involves the use of urethane and isocyanurate group modified 2,4- and/or 2,6toluene diisocyanate mixtures as the polyisocyanate component to improve the flowability of the reaction mixture without adversely affecting the mechanical properties of the resulting molded articles.
