Abstract
Un dispositivo de separación de fibras huecas que comprende un haz de fibras huecas constituido por una pluralidad de fibras huecas finas cuyas porciones extremas están encapsuladas en una placa tubular y cuyos extremos de fibra abiertos terminan en una cara de placa tubular, estando el haz resultante herméticamente cerrado dentro de una envoltura para formar una celda de separación que tiene una o más aberturas para fluido que permiten el paso de un fluido a través de las fibras y de otro alrededor de las fibras sin mezclado de los dos fluidos, comprendiendo dicha placa tubular una composición de poliuretano curada constituida esencialmente por: A) un prepolímero que comprende el producto de reacción de aceite de ricino y polioxipropilenglicol con al menos un mol de diisocianato orgánico por cada grupo hidroxi del polialcohol, y B) un agente de reticulación que comprende el éster de i) un alcohol polivalente que contiene 2 ó 3 grupos hidroxi, y ii) un ácido alifático de al menos 12 átomosde carbono y uno o más grupos hidroxi y/o epoxi por molécula y mezclas de dicho éster y aceite de ricino soplado.
