Abstract

Patente de Invenção: <B>"PROCESSO E CATALISADOR PARA A PREPARAçãO DE POLIOLEFINAS COM PESO MOLECULAR MéDIO ATé ULTRA-ALTO"<D>. A invenção refere-se a um processo para a preparação de poliolefinas com peso molecular médio até ultralato mediana homo- ou copolimerização de olefinas, especialmente etileno com outras alfa-olefinas na presença de um catalisador misto de Ziegler-Natta do tipo metaloceno suportado sobre um material polímero orgânico para o acabamento de artigos moldados, por exemplo, mediante extrusão, fundição por injeção, insuflação de folhas, prensagem por sinterização ou extrusão Ram. O catalisador de acordo com a invenção contém como material polímero orgânico um copolímero de estireno-divinilbenzeno parcialmente clorometilado, um composto complexo suportado sobre o mesmo, que contém Mg, Al e metais de transição do IV° subgrupo, bem como produtos de reação do último com outros compostos orgânicos e metais de transição do IV° subgrupo.
