ABSTRACT:
The use of polyol derivatives with at least two alcoholic hydroxy groups and at least one fatty acid residue per molecule obtainable by reacting a starting polyol with a fatty acid or a fatty acid derivative, which can be obtained by using as a starting polyol diethanolamine, triethanolamine, diisopropanolamine, triisopropanolamine, dibutanolamine, and reaction products of ethylene oxide and/or propylene oxide with ethanolamine, isopropanolamine, butanolamine, or primary or secondary, aliphatic or aromatic amines, as internal lubricants and/or polyol with internal lubricant properties in the production of molded polyurethane parts is described. In this manner a much more uniform distribution of the internal mold lubricant and thus an increase in the ductility of the reaction mixture can be achieved, and even crosslinked polyurethane profiles can be produced by extrusion.
