Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA MANUFACTURAR DE FORMA CONTINUA (CO-)POLIMERO DE ETILENO EN UNA FASE GASEOSA EN UNA ZONA DE POLIMERIZACION A TRAVES DE LA CUAL PASA UNA MEZCLA DE REACCION ESENCIALMENTE GASEOSA QUE COMPRENDE LOS (CO-)MONOMEROS. ADEMAS, EL PROCESO COMPRENDE LA TRANSFERENCIA DE UNA MEZCLA (A) FORMADA POR LA MEZCLA DE REACCION GASEOSA Y EL (CO-)POLIMERO SOLIDO EN UNA ZONA DE DESPRESURIZACION, Y LA SEPARACION DE LA MEZCLA (A) EN UNA FASE SOLIDA (B) Y UNA FASE GASEOSA (C) QUE SE HACE RETORNAR A LA ZONA DE POLIMERIZACION. LA FASE SOLIDA (B) SE EXPONE A (1) AL MENOS UN LAVADO NO DESACTIVANTE CON RESPECTO A LOS RESIDUOS CATALITICOS ACTIVOS, Y SUBSECUENTEMENTE (2) A UN LAVADO DE DESACTIVACION CON UNA MEZCLA GASEOSA DE NITROGENO, AGUA Y OXIGENO. EL (CO-)POLIMERO ASI OBTENIDO TIENE MUY BAJOS CONTENIDOS DE (CO-)MONOMEROS NO REACCIONADOS Y COMPUESTOS ORGANICOS VOLATILES, Y EXHIBE UN ALTO INDICE DE BLANCURA Y UNA LARGA ESTABILIDAD TERMICA A LO LARGO DEL TIEMPO.
