Abstract

PROCEDIMIENTO DE OBTENCION DE POLIMEROS DE ETILENO. CONSISTE EN EFECTUAR LA POLIMERIZACION DEL ETILENO EN PRESENCIA DE UN SISTEMA CATALITICO CONSTITUIDO POR UN COMPUESTO HALOGENADO DE METAL DE TRANSICION Y UN ACTIVADOR ELEGIDO ENTRE LOS HIDRUROS Y LOS COMPUESTOS ORGANOMETALICOS DE LOS GRUPOS I A III. SE EMPLEA UN PRIMER REACTOR A UNA PRESION DE 800 A 200 BARES Y A UNA TEMPERATURA DE 160 A 260GC, Y UN SEGUNDO REACTOR A UNA PRESION DE 300 A 600 BARES Y A UNA TEMPERATURA COMPRENDIDA ENTRE 240 Y 340GC. LA POLIMERIZACION TIENE LUGAR EN AUSENCIA DE HIDROGENO Y ALIMENTANDO EL REFLUJO DE ETILENO DE SEGUNDO REACTOR QUE REPRESENTA DEL 17 AL 69 POR 100 DEL FLUJO TOTAL DE ALIMENTACION DE ETILENO. EL CATALIZADOR DE LA POLIMERIZACION SE DESACTIVA INYECTANDO AL MENOS UNA SAL ALCALINA O ALCALINO-TERREA DE ACIDO CARBOXILICO. EL ETILENO ES COPOLIMERIZADO CON ALFA-OLEFINA.
