Abstract
Procédé en continu d'extraction de l'acide polyphosphoric d'un filament dopé au polybenzazole. Ce procédé comprend les étapes suivantes: (a) le filament dopé est exposé à l'eau ou à un mélange d'eau et d'acide polyphosphorique dans des conditions suffisantes pour abaisser la teneur en phosphore du filament à moins de 10,000 ppm en poids; puis (b) le filament dopé est soumis à une solution aqueuse d'une base non-organique dans des conditions suffisantes pour convertir au moins 50 % des groupes acides polyphosphoriques présents dans le filament en un sel de la base et de l'acide. On a constaté que le fait de soumettre un filament à une solution de base après l'avoir lavé pour extraire la plus grande partie du phosphore résiduel entraîne une amélioration de la résistance initiale à la traction de ce filament ainsi qu'une amélioration de la préservation de la résistance à la traction et/ou du poids moléculaire (du polymère polybenzazole) après une exposition à la lumière et/ou à des températures élevées.
