Abstract

Patente de Invenção: <B>''PROCESSO PARA PRODUZIR MATERIAL DE POLIETILENO HOMOGêNEO NA PRESENçA DE UM CATALISADOR''<D> A presente invenção diz respeito à um processo para produzir materiais de polietileno homogêneos e processos para filmes de alta densidade, média densidade e alta densidade deles. O processo consiste em produzir uma composição de polietileno em uma seq³ência de reação de multi-estágios com sucessivos estágios de polimerização na presença de um sistema de catalisador polimerizador de etileno. De acordo com a invenção, o processo é realizado usando-se um catalisador não-suportado contendo magnésio e titânio como constituintes ativos, em pelo menos um estágio de polimerização em "loop" e em pelo menos um estágio de polimerização em fase gasosa e operado com diferentes quantidades de hidrogênio e comonómeros para produzir uma porção de alto peso molecular em um dos estágios de polimerização e uma porção de baixo peso molecular em outro estágio de modo a fornecer uma composição de polietileno com uma parte de baixo peso molecular tendo uma MFR~2~ de 250 g/10 min ou mais. Por meio do processo é possível obter material de polietileno bimodal homogêneo.
