Abstract

"CATALISADOR BIMETáLICO, PROCESSO DE POLIMERIZAçãO, E POLIOLEFINAS BIMODAIS DO MESMO". A presente invenção refere-se a catalisadores bimetálicos, e processos de produzir um catalisador bimetálico compreendendo um catalisador de Ziegler-Natta modificado e um metaloceno, em uma modalidade o processo incluindo combinar: (a) um catalisador de Ziegler-Natta compreendendo um haleto ou óxido de metal do Grupo 4, 5 ou 6, opcionalmente incluindo um composto de magnésio, com (b) um composto modificador ('modificador'), em que o composto modificador é um composto de alquila do Grupo 13, para formar um catalisador de Ziegler-Natta modificado. Também fornecido é um processo de polimerização de olefina usando o catalisador bimetálico da invenção. O catalisador de Ziegler-Natta modificado é preferivelmente não-ativado, isto é, é sozinho não-reativo para polimerização de olefina. Em uma modalidade, a razão molar do metal do Grupo 13 (do modificador) para o haleto ou óxido de metal do Grupo 4, 5 ou 6 é menor que 10:1 em uma modalidade. Os catalisadores bimetálicos da presente invenção são úteis em produzir polímeros bimodais, particularmente polietileno bimodal, tendo uma Polidispersabilidade (Pm/Nm) de 12 a 50. Estas poliolefinas bimodais são úteis em tais artigos como canos e filmes.
