Abstract

Las modalidades de la presente descripción se refieren a un método de preparación de composiciones de polietileno, que comprende la polimerización de etileno en un primer reactor de fase gaseosa y la polimerización de etileno en un segundo reactor de fase gaseosa en presencia de hidrógeno, donde al menos uno de los reactores de fase gaseosa comprende una primera y una segunda zona de polimerización, donde la presión de hidrógeno de las zonas de polimerización primera y segunda es diferente, de modo que al menos una parte de la segunda cantidad de etileno se desplaza a través de las zonas de polimerización primera y segunda y se impide el ingreso total o parcial de la mezcla gaseosa de cada zona de polimerización a la otra zona.
