Abstract

L'invention concerne un procédé de préparation des polybenzoxazoles qui consiste à faire réagir des bis-ortho-aminophénols sur des halogénures d'acides dicarboxyliques, à une température de - 20 degrés à + 100 degrés C, dans un milieu de solvant organique pour former un mélange réactionnel contenant un polyoxyamide que l'on isole du mélange et que l'on soumet à un vieillissement thermique à une température de 200 à 400 degrés C. Comme bis-ortho-aminophénols on utilise un mélange d'un bis-ortho-aminophénol répondant à la formule générale suivante :
