Abstract
UNA FIBRA HUECA DE POLIESTERAMIDA, UTIL EN EL PROCEDIMIENTO DE DIALISIS Y EN LOS PROCESOS DE ULTRAFILTARCION EN GENERAL, SE FORMA MEDIANTE UNA POLIESTERAMIDA CON UNIDADES REPETIDAS DE (TATE)N (DONDE T ES EL RADICAL DEL ACIDO TEREFTALICO; A ES EL RADICAL DE ETILENDIAMINA; Y E ES EL RADIACAL DE HEXANODIOL) MUSTRA UN DIAMETRO EXTERIOR DE 200 A 1.000 (MU)M, UN ESPESOR DE PAREDES DE 20 A 200 (MU)M, UN VALOR DE PERMEABILIDAD AL AGUA DE HASTA 7,5 L/M2/H PARA UN (DELTA)P DE 300 MM DE HG Y UNA BUENA PERMEABILIDAD PARA SUSTANCIAS QUE TIENEN UN PESO MOLECULAR DE HASTA 17.000 APROXIMADAMENTE. TAL FIBRA SE OBTIENE POR MEDIO DE UN PROCEDIMIENTO QUE COMPRENDE LAS SIGUIENTES ETAPAS, LLEVADAS A CABO SECUENCIALMENTE: PREPARACION DE UNA DISOLUCION DE POLIESTERAMIDA (TATE)N EN UN DISOLVENTE CONSTITUIDO POR ACIDO FORMICO A UNA CONCENTRACION MAYOR QUE 99 % APROXIMADAMENTE O CONSTITUIDO POR UNA DISOLUCION DE CLORURO DE LITIO EN DIMETILFORMAMIDA O DIMETILACETAMIDA; EXTRUSION DE DICHA DISOLUCION A TRAVES DE UN HILADOR QUE TIENE UNA SECCION TRANSVERSAL DE FORMA ANULAR Y COAGULACION DE LA FIBRA EN UN BAÑO DE COAGULACION ACUOSO, CON LA POSIBLE INTRODUCCION DE UN LIQUIDO COAGULANTE ACUOSO AL INTERIOR DE LA ABERTURA ANULAR DEL HILADOR; LAVAR CON AGUA Y RECUPERAR LA FIBRA HUECA ASI OBTENIDA.
