Abstract

"PROCESSO PARA A MOLDAGEM POR SOPRO, EXTRUSãO OU PRODUçãO DE FILME SOPRADO EXTRUSADO DE UM POLIETILENO". A presente invenção se refere a polietilenos produzidos a partir de etileno e uma série de <244>-olefinas mediante o emprego de um catalisador que copolimeriza etilenos e <244>-olefinas que têm geralmente excelentes características de processamento por fusão, especialmente nos usos em que a viscosidade elevada a cisalhamento zero e baixa viscosidade a alto grau de cisalhamento são desejáveis. Esses polietilenos são preferencialmente produzidos mediante a formação das <244>-olefinas in situ a partir de etileno durante o processo de polimerização. Os polietilenos são especialmente úteis a moldagem por sopro, extrusão ou processos de filme soprado extrusado.
