The use of polyol derivatives obtainable by reacting a starting polyol with a fatty acid or a fatty acid derivative with at least 2 alcoholic hydroxyl groups and at least one fatty acid residue per molecule is described, which is carried out using 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 starting polyol, as internal release agents and / or polyol with release properties in the production of molded parts made of polyurethane. In this way, a much more uniform distribution of the inner mold release agent and thus an increase in the formability of the reaction mixture and also crosslinked polyurethane profiles can be produced by extrusion. |
