Abstract
La présente invention a pour objet la préparation de solutions de polystyrylpyridine. Le procédé selon l'invention consiste à effectuer la polycondensation de l'aldéhyde téréphtalique et d'au moins un dérivé pyridinique portant au moins deux substituants méthyles réactifs à une température comprise entre 150"C et 200 degrés C, en présence d'un excès de dérivés pyridiniques. La réaction de polycondensation est arrêtée lorsque le taux de condensation est égal à au moins 50 %; l'excès de dérivés pyridiniques est alors partiellement éliminé et le polycondensat est dissous dans un solvant choisi parmi la méthyléthylcétone, l'acétate d'éthyle, le chlorure de méthylène, le trichlorethylène, le chlorobenzene, le n-propanol. Les solutions de polystyrylpyridine obtenues par le procédé de l'invention sont utiles pour la fabrication de matériaux composites.
