Abstract

Un procédé permet de fabriquer des résines de polyester et d'alkyde à partir d'acides carboxyliques bifonctionnels et/ou à plus haute fonctionnalité et/ou de leurs dérivés et/ou d'alcools bifonctionnels et/ou à plus haute fonctionnalité. La réaction se produit dans des réacteurs à bacs d'agitation pourvus de colonnes de rectification et exploités par intermittence. Afin d'améliorer le transport des produits de condensation, un convoyeur distribue un agent entraîneur dans le mélange de réaction, au-dessous de son niveau de surface, pendant toute la durée de la réaction. En outre, la réaction de condensation se produit sous une pression absolue comprise entre 1,5 et 10 bars au moins jusqu'à ce que la vitesse maximale de réaction soit atteinte. Ensuite, pendant une deuxième phase de réaction, la pression diminue avec un gradient compris entre -0,05 bar/h et -5 bar/h jusqu'à la pression atmosphérique. La réaction se poursuit alors sous une pression normale jusqu'à ce que le produit présente les propriétés voulues. La température de réaction se situe entre 180° et 320°C. Ce procédé permet notamment de raccourcir la durée du traitement et d'obtenir par conséquent des produits moins soumis à des contraintes thermiques qui présentent des propriétés améliorées.
