Abstract
On prépare les fils en faisant subir une extrusion en 10 à un mélange homogène réalisé en 8, constitué par un polymère fusible provenant de 5 et par un liquide inerte provenant de 1, les deux constituants formant un système binaire qui présente à l'état physique liquide un domaine de miscibilité totale et un domaine de non miscibilité, à une température supérieure à la température de démixtion, dans un bain 15 qui renferme le liquide inerte et qui possède une température inférieure à la température de démixtion. On peut extraire les fils par lavage avec un solvant. On peut disposer une colonne d'air entre la filière et le bain. Les fils sont en particulier appropriés en tant que substrats ayant une action de longue durée et en tant que matière isolante.
