Abstract

Patente de Invenção: <B>''CATALISADORES POLIMéRICOS SUPORTADOS PARA POLIMERIZAçãO DE OLEFINAS''<D>. A invenção descrita provê um processo de polimerização de alta densidade de partícula, de baixa deposição e uma composição de co-catalisador ativador suportado de polimerização de olefinas compreendendo um polímero reticulado em contas tendo uma área superficial de cerca de 1 a 20 m²/g ao qual estão ligados vários ânions não-coordenantes, em que o suporte polimérico compreende ligandos ligados covalentemente aos átomos centrais de metal ou metalóide dos referidos ânions e um número adequado de espécies catiónicas para que seja obtida uma carga balanceada. A invenção provê também uma composição catalisadora de polimerização de olefina compreendendo o produto de reação de a) o ativador co-catalisador anterior e b) um composto organometálico de metal de transição tendo ligandos auxiliares, pelo menos um ligando lábil susceptível a extração por protonação e pelo menos um ligando lábil no qual um monómero olefínico pode se inserir para polimerização. Em uma concretização preferido o suporte polimérico tem área superficial de <243> 10 m²/g e é particularmente adequado para uso com compostos catalisadores organometálicos de metal de transição de alta atividade.
