Abstract
Un procedimiento mejorado para producir fibras sintéticas acrílicas, caracterizado por extruir, a través de orificios de hilado en una atmósfera caliente y húmeda, una composición polímera de acrilonitrilo homogénea en un estado sustancialmente fundido que se obtiene por polimerización de acrilonitrilo solo o de una mezcla de monómeros constituida por acrilonitrilo como componente principal y al menos un monómero etilénicamente insaturado diferente como componente restante, en un sistema en el que está presente agua en una cantidad comprendida dentro del intervalo que va desde 3 a 30 por ciento en peso basado en el peso total del o de los monómeros y el agua, a una presión igual al menos a la presión autogenerada, a temperaturas superiores a 80ºC, de tal modo que del 45 al 90 por ciento en peso de dicho o dichos monómeros se convierte en un polímero.
