Abstract
La presente invención se refiere a un método para producir pasta de para-aramida, caracterizada porque consiste de: formar una solución que se polimeriza activamente, líquida que contiene cadenas poliméricas de un para-aramida poniendo en contacto con agitación, cantidades esencialmente estequiométricas de un haluro de diácido aromático que consiste esencialmente de un haluro de diácido aromático para-orientado, y diamina aromática que consiste esencialmente de una diamina aromática para-orientada en un sistema de solvente de amida esencialmente anhídro; someter la solución líquida, cuando la viscosidad inherente de la para-aramida es entre aproximadamente 1 y aproximadamente 4, a un flujo de orientación que produce una solución líquida ópticamente anisotrópica que contiene dominios de cadenas poliméricas dentro de las cuales las cadenas poliméricas de la para-aramida se orientan esencialmente an la dirección del flujo: incubar la solución líquida anisotrópica durante por lo menos un período de duración suficiente para que la solución anisotrópica se convierta en un gel, la incubación se inicia cuando la solución líquida ópticamente anisotrópica tiene una viscocidad suficiente para mantener generalmente la orientación de las cadenas poliméricas en la solución líquida anisotrópicas, hasta que la solución líquida se convierta en un gel; cortar el gel transversalmente a intervalos seleccionados con respecto a la orientación de las cadenas poliméricas en el gel; y aislar la pasta de para-aramida del gel.
