Abstract

Patente de Invenção: <B>"PROCESSO DE COPOLIMERIZAçãO DE ETILENO"<D>. Esta invenção é um processo em solução para preparação de copolímeros etileno-<244>-olefina-diolefina compreendendo o contato de etileno, um ou mais monómeros <244>- olefínicos, um ou mais monómeros dieno cíclicos, com uma composição de catalisador compreendendo um composto bis(ciclopentadienil) zircónio ligado em ponte tendo um ligante ciclopentadienila não substituído, um ligante ciclopentadienila multiplamente substituído, os referidos ligantes ligados em ponte por um grupo ponte covalente contendo um ou mais elementos do Grupo14, e dois ligantes reativos de ativação uninegativos e um composto ativador de catalisador. O processo da invenção exibe alta atividade catalisadora, alta incorporação de comonómero e altas taxas de conversão de monómero dieno, e é particularmente adequado para a preparação de elastómeros de monómeros etileno-propileno ou etileno-propileno-dieno elastoméricos.
