Abstract

PROCEDIMIENTO MEJORADO Y APARATO PARA LA PRODUCCION DE UN POLIESTER U OTRO POLIMERO DE CONDENSACION. ESPECIALMENTE, LA POLIMERIZACION SE REALIZA EN UN UN RECIPIENTE DE REACCION CON UN AGITADOR DISEÑADO ESPECIALMENTE QUE EXPONE EL POLIMERO FUNDIDO QUE RELLENA PARCIALMENTE EL RECIPIENTE DE REACCION, A UN GAS INERTE QUE FLUYE A TRAVES DEL RECIPIENTE. DICHO AGITADOR COMPRENDE UNA PLURALIDAD DE ELEMENTOS QUE ELEVAN UNA PORCION DE UN POLIMERO FUNDIDO EN EL RECIPIENTE DE REACCION Y GENERAN PELICULAS DE DICHO POLIMERO FUNDIDO QUE SE EXTIENDEN EN PLANOS PARALELOS AL EJE DEL AGITADOR Y AL FLUJO DEL GAS A TRAVES DEL RECIPIENTE DE REACCION. EN UN PROCESO PREFERIDO, SE PONE EN CONTACTO UN POLIMERO FUNDIDO DE BIS (2 - HIDROXIETIL) TEREFTALATO, O SUS OLIGOMEROS DE BAJO PESO MOLECULAR, QUE SE OBTIENEN ESTERIFICANDO ACIDO TEREFTALICO O TRANSESTERIFICANDO DIMETIL TEREFTALATO CON ETILEN GLICOL, CON UN GAS INERTE A PRESION APROX. ATMOSFERICA, A FIN DE ELIMINAR LOS SUBPRODUCTOS DE REACCION Y FACILITAR LA POLIMERIZACION.
