Abstract
La présente invention a pour objet la préparation de solutions de polystyrylpyridine. Le procédé selon l'invention consiste à effectuer la polycondensation d'au moins un dialdéhyde aromatique, préférentiellement l'aldéhyde téréphtalique, et d'au moins un dérivé pyridinique portant au moins deux substituants méthyles réactifs à une température comprise entre 150 degrés C et 200 degrés C, sans excès de dérivés pyridiniques. La réaction de polycondensation est arrêtée lorsque le taux de condensation est égal à au moins 40 % ; le polycondensat est alors dissout dans un solvant choisi parmi la méthyléthylcétone, l'acétate d'éthyle, le chlorure de méthylène, le trichloréthylène, le chlorobenzène, le n-propanol, et de préférence dans un mélange de méthyléthylcétone et de n-propanol. Les solutions de polystyrylpyridine obtenues par le procédé de l'invention sont utile pour la fabrication de matériaux composites caractérisés par de très bonnes propriétés mécaniques, un excellent comportement à haute température, au feu, et aux agents chimiques et atmosphériques.
