Abstract

PROCEDIMIENTO PARA LA OBTENCION DE COMPOSICIONES A BASE DE POIPARAFENILNOTEREFTALAMIDA Y SU TRANSFORMACION EN FIBRAS. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, EN UNA PRIMERA ETAPA SE HACE REACCIONAR CLORURO DE TEREFTALOILO EN CANTIDAD SENSIBLEMENTE ESTEQUIOMETRICA SOBRE UNA SOLUCION DE PARAFENILENODIAMINA, EN CANTIDAD TAL QUE SE PUEDA FORMAR UNA COMPOSICION DE AL MENOS UN 5% EN PESO DE PARAFENILENOTEREFTALAMIDA EN UNA MEZCLA HOMOGENEA DE N-METILPIRROLIDONA, DE CLORURO DE CALCIO O LITIO Y DE UNA AMINA TERCIARIA; SEGUNDA, SE AGREGA EVENTUALMENTE UNA CANTIDAD DE AMINA TERCIARIA, SIN SOBREPASAR EL LIMITE DE SOLUBILIDAD DEL CLORURO DE CALCIO; Y POR ULTIMO, EN UNA SEGUNDA ETAPA LA COMPOSICION OBTENIDA SE TRANSFORMA EN FIBRAS POR EXTRUSION O COLADA.
