Patent

CA 2110925

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 Image where m = 1 to 3 n ~ 3 and RI, RII, RIII and RIV are identical or different and, independently of one another, are hydrogen or C1- to C4-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.

L'invention concerne des polyétherestérols obtenus par condensation d'un acide carboxylique polyfonctionnel avec un composant alcool. Le composant alcool comprend un mélange d'alcanediols et d'étherdiols de la formule Image , où m = 1 à 3, n est 3, et RI, RII, RIII et RIV sont identiques ou différents et indépendamment l'un de l'autre un hydrogène ou un alkyle en C1-C4; le rapport entre les groupes éther et ester dans le polyétherestérol est de l'ordre de 0,3:1 à 1,5:1, ce qui convient en particulier pour la préparation de polyuréthanes moins embués.
