Abstract

"MéTODO PARA PREPARAçãO DE POLIOLEFINAS". Descreve-se um método para preparação de poliolefinas de distribuição em peso molecular bimodal tendo uma propriedade alvejada, tal como, índice de fluxo, relação de fluxo de fusão, ou frações em peso de componentes em peso molecular mais elevado ou menor. O método emprega um catalisador bimetálico contendo um componente de metaloceno e um componente de não-metaloceno, e as atividades das porções de metaloceno e não-metaloceno são controladas ajustando-se a relação de organoalumínio e cocatalisador de metilaluminoxano modificado. O método provê a monitoração e ajuste de propriedades de poliolefina em uma base de tempo real, quando a poliolefina está formando-se.
