The invention relates to polyetheresterols, as are obtained by condensation of polyfunctional carboxylic acids with an alcohol component, and the alcohol component is a mixture of alkanediols and etherdiols of the general formula With m = 1 to 3 n ≧ 3 and R I , R II , R III , R IV - independently of one another, identical or different, hydrogen atom and / or C₁- to C₄-alkyl groups, included, the ratio of ether to ester groups in the polyetheresterol in the range from 0.3: 1 to 1.5: 1.n n n The polyetheresterols according to the invention are particularly suitable for the production of polyurethanes with reduced fog development. |
