Abstract

Procedimiento perfeccionado de polimerización del etileno bajo alta presión, en presencia de hidrógeno, a una temperatura de 180 a 340º C bajo una presión de 200 a 2500 bares por medio de un sistema catalítico tipo Ziegler en por lo menos un reactor agitado que comprende al menos una primera zona reaccional y por lo menos una segunda zona reaccional, consistente en descomprimir y enviar la mezcla reaccional hacia un primer separador bajo una presión de 80 a 400 bares, enviar la fase líquida proveniente del primer separador hacia una primera tolva bajo una presión de 1 a 15 bares.
