Abstract

PREPARATION DE POLYESTERS A BASE DE DICARBOXYLATES AROMATIQUES D'ALKYLENE. IL CONSISTE A POLYCONDENSER UN PRECURSEUR DE POLYESTER, COMPOSE PRINCIPALEMENT DE TEREPHTALATE DE BIS(HYDROXYALKYLE) OU DE SES OLIGOMERES, INTRODUIT EN CONTINU DANS UN REACTEUR A POLYCONDENSATION, SIMULTANEMENT AVEC DE LA VAPEUR D'ALKYLENE GLYCOL, QUI EST INSUFFLEE DANS LA PHASE GAZEUSE A L'INTERIEUR DE CE REACTEUR. CET ALKYLENE GLYCOL, EN FAVORISANT L'ELIMINATION DES PRODUITS DE SUBLIMATION, PERMET UN FONCTIONNEMENT EN CONTINU DE PLUS LONGUE DUREE, ET L'OBTENTION DE PROPRIETES SUPERIEURES POUR LE POLYESTER.
