Abstract

METODO DE COPOLIMERIZACION DE ETILENO CON AL MENOS UN COMONOMERO CONSTITUIDO POR UNA 1-OLEFINA QUE TIENE DE 3 A 8 ATOMOS DE CARBONO EN SU CADENA PRINCIPAL. COMPRENDE LA REACCION DE UNA MEZCLA GASEOSA DE ETILENO Y EL COMONOMERO EN PRESENCIA DE UN CATALIZADOR DE COPOLIMERIZACION A BASE DE METAL DE COORDINACION EN UN SISTEMA DE REACCION CONSTITUIDO POR UN REACTOR Y UN SISTEMA DE RECICLO QUE FUNCIONA A PRESION Y TEMPERATURA INFERIORES A LA DEL REACTOR. LA TEMPERATURA DE REACCION ESTA COMPRENDIDA ENTRE 149JC Y 315JC Y LA PRESION ENTRE 700 Y 1.400 KG/CM. LA MEZCLA GASEOSA DE REACCION CONTIENE UN GAS INERTE DE BAJO PESO MOLECULAR COMO MODIFICADOR DE LA RELACION. TIENE APLICACIONES PARA LA PRODUCCION DE RESINAS DE COPOLIMERO DE POLIETILENO DE BAJA DENSIDAD.
