    摘要: The invention relates to polyetheresterols obtained by condensation of a polyfunctional carboxylic acid with an alcohol component, wherein the alcohol component comprises a mixture of alkanediols and etherdiols of the formula ##STR1## where m=1 to 3n.gtoreq.3 andR.sup.I, R.sup.II, R.sup.III and R.sup.IV are identical or different and, independently of one another, are hydrogen or C.sub.1 - to C.sub.4 -alkyl,and the ratio between ether and ester groups in the polyetheresterol is in the range from 0.3:1 to 1.5:1, which are suitable, in particular, for the preparation of polyurethanes having reduced fogging.
