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.The invention relates to cured polyurethanes. Polyurethanes include, for example, the reaction product 1) of the reaction product of a) a polyester prepared from difunctional ingredients comprising at least one dicarboxylic acid and at least one difunctional reagent in which the functional groups are hydroxy groups, said polyester having a hydroxy number of 40 to 100 and an acid number of 0 to 7, and b) an arylene diisocyanate, and 2) a crosslinking agent consisting essentially of an ester of a polyalcohol having two or three hydroxy groups and an aliphatic hydroxy- and / or epoxy acid having at least 12 carbon atoms. Application: hollow fiber separator device.
