Abstract

PROCEDIMIENTO PARA PREPARAR UNA FIBRA DE POLIMERO DE ACRILONITRILO.COMPRENDE: A) PREPARAR UNA COMPOSICION DE HILATURA DE UN POLIMERO DE ACRILONITRILO FORMADOR DE FIBRA EN UNA SOLUCION ACUOSA DE SAL DE TIOCIANATO, CON UNA COMPOSICION DE 80 A 95 EN PESO DE ACRILONITRILO, 5 A 12 EN PESO DE METACRILATO DE METILO Y EL RESTO CONSTITUIDO POR UN COMONOMERO LIBRE DE PUNTOS DE TEÑIDO ACIDOS Y TENIENDO EL POLIMERO UN PESO MOLECULAR DE 9.000 A 14.750. LA COMPOSICION DE HILATURA PRESENTA UNA CONCENTRACION DE POLIMERO DE 12,5 A 16 EN PESO EN UNA SOLUCIONACUOSA DE SAL DE TIOCIANATO EN CONTENIDO DE 38 A 45 EN PESO, TENIENDO LA SOLUCION DE HILATURA UNA VISCOSIDAD DE 28 A 60 POISES, DETERMINADA POR EL METODO DE LA CAIDA DE BOLA A 40JC; B) EXTRUIR LA SOLUCION DE HILATURA EN UNA SOLUCION ACUOSA DILUIDA DE SAL TIOCIANATO, PARA FORMAR UNA FIBRA GELIFICADA HUMEDA; C) LAVAR Y ESTIRAR LA FIBRA GELIFICADA HUMEDA PARA SEPARAR LA SAL TIOCIANATO Y PROPORCIONAR ORIENTACION POLIMERICA; Y D) DESTRUIR A CONTINUACION LA ESTRUCTURA GELIFICADA HUMEDA.
