Abstract

Linvention concerne des polyuréthanes durcis. Les polyuréthanes comprennent par exemple le produit de réaction 1) du produit de la réaction de a) un polyester préparé à partir d'ingrédients difonctionnels comprenant au moins un acide dicarboxylique et au moins un réactif difonctionnel dans lequel les groupes fonctionnels sont des groupes hydroxy, ledit polyester ayant un indice d'hydroxy de 40 à 100 et un indice d'acide de 0 à 7, et b) un arylène diisocyanate, et 2) d'un agent de réticulation consistant essentiellement en un ester d'un polyalcool doté de deux ou trois groupes hydroxy et d'un hydroxy- et/ou époxyacide aliphatique ayant au moins 12 atomes de carbone. Application : dispositif séparateur à fibres creuses.
