摘要：The use of polyol derivatives with at least two alcoholic hydroxy groups and atleast one fatty acid residue per molecule obtainable by reacting a starting polyol with afatty acid or a fatty acid derivative, which can be obtained by using as a starting polyoldiethanolamine, triethanolamine, diisopropanolamine, triisopropanolamine,

dibutanolamine, and reaction products of ethylene oxide and/or propylene oxide withethanolamine, isopropanolamine, butanolamine, or primary or secondary, aliphatic oraromatic amines, as internal lubricants and/or polyol with internal lubricant properties inthe production of molded polyurethane parts is described. In this manner a much moreuniform distribution of the internal mold lubricant and thus an increase in the ductility ofthe reaction mixture can be achieved, and even crosslinked polyurethane profiles can beproduced by extrusion.
