Abstract
Procédé de préparation de filaments de polybenzazole qui consiste à extruder des filaments d'une filière (1) présentant au moins cent orifices disposés de manière à former un motif annulaire (2) autour du centre de ladite filière (1), le centre et au moins deux sections radiales (3) de la filière (1) n'étant pas dotés d'orifices et présentant une largeur moyenne correspondant à au moins trois fois le diamètre minimum des orifices, et à étirer les filaments à travers une chambre de trempe, un flux de gaz sensiblement radial étant produit dans la filière (1) depuis au moins deux directions différentes.
