Abstract

um processo de polimerização em lama para preparação de polietileno na presença de um catalisador de ziegler e um alquilaluminado em pelo menos um reator de polimerização, processo no qual o meio de suspensão compreende uma concentração de alquilaluminado e é reciclado para polimerização, a concentração de alquilaluminado no meio de suspensão reciclado é determinada e a quantidade de alquilaluminado fresco introduzido na polimerização é ajustada a fim de manter uma concentração de alquilaluminado desejada no meio de suspensão reciclado.
