Abstract

Un proceso de polimerización de alta presión para formar un polímero basado en etileno que incluye los pasos de: A) inyectar un primer alimento que contiene un sistema de agente de transferencia de cadena (sistema CTA) y etileno dentro de una primera zona del reactor autoclave que opera bajo condiciones de polimerización para producir un producto de reacción de la primera zona, el sistema CTA de la primera zona del reactor tiene una actividad de transferencia Z1; y B) (i) transferir al menos parte del producto de reacción de la primera zona a una segunda zona del reactor seleccionada de una segunda zona del reactor autoclave o de una zona del reactor tubular y que opera bajo condiciones de polimerización y optativamente, (ii) inyectar en ese momento un segundo alimento en la segunda zona del reactor para producir un producto de reacción de la segunda zona, siempre que al menos uno de los productos de primera zona del reactor y el alimento recientemente inyectado contengan un sistema CTA con una actividad de transferencia de Z2; y siempre que la proporción de Z1:Z2 sea mayor a 1.
