Abstract

PROCESSO PARA A POLIMERIZAÇÃO DE PROPILENO NA PRESENÇA DE UM CATALISADOR DE POLIMERIZAÇÃO E PROCESSO PARA A PRODUÇÃO DE TUBOS. É descrito na presente invenção um processo para a polimerização de propileno na presença de um catalisador de polimerização por copolimerização de propileno com um comonômero selecionado a partir do grupo de etileno e C4-C10 alfa-olefinas, em três etapas de polimerização. O polímero produzido na primeira etapa de polimerização tem a maior taxa de escoamento em fusão e o teor de comonômero mais baixo. O polímero produzido na última fase de polimerização tem o índice de fluxo de fusão mais baixo e o maior teor de comonômero. A composição do polímero produzido pelo processo tem boas propriedades mecânicas e pode ser usada para a produção de tubos. O processo tem uma boa produtividade.
