Abstract

<B>"PROCESSO PARA POLIMERIZAçãO DE OLEFINAS"<D> A presente invenção se refere a misturas de diferentes poliolefinas ou poliolefinas ramificadas que podem ser produzidas por polimerização direta, preferencialmente simultânea, de uma ou mais olefinas polimerizáveis, utilizando dois ou mais metais de transição contendo sistemas catalisadores de polimerização ativos, um dos quais contém preferencialmente metais de transição em forma de complexo com ligantes selecionados. Os produtos de poliolefina podem possuir polímeros cujo peso molecular, distribuição de peso molecular, cristalinidade ou outros fatores variam e que são úteis como resinas de moldagem e para filmes.
