Abstract

Un procedimiento para la producción de composiciones de polietileno en la presencia de un sistema catalítico de catalizador y cocatalizador depolimerización de etileno en una secuencia de reacción de múltiples etapas consistentes en sucesivaspolimerizaciones de fase líquida y fase gaseosa. Elprocedimiento comprende por lo menos una secuencia de reaccion contínua, en la cual en la primera etapa se polimerizan etileno y opcionalmente hidrógeno ycomonómero en un reactor de lazo cerrado, enun medio de hidrocarburo de bajo punto de ebullición, en la presencia de catalizador y cocatalizador depolimerización de etileno, siendo el tiempo de permanencia y la temperatura de reacción tales que la proporción del polímero de etileno producido en elreactor desde el producto final del procedimiento está entre 1 y 20% en peso, siendo la mezcla de reacción removida de esta etapa transferida a una segundaetapa donde la polimerización es continuada en un reactor de lazo cerrado mediante el agregado de etileno, hidrógeno y opcionalmente hidrocarburo inerte,comonómeros y cocatalizadores, siendo el tiempo de permanencia de por lo menos 10 minutos, siendo la mezcla de reacción removida de reactor de lazo cerrado,siendo por lo menosuna parte esencial del medio de reacción removida y el polímero transferido a una tercera etapa donde se lleva a cabo lapolimerización en un reactor de fase gaseosa en la presencia del agregado etileno y opcionalmente hidrógeno, comonómeros y cocatalizadores.
