Abstract

POLIETILENO DE ALTA DENSIDADE LINEAR COM ALTA ROBUSTEZ E ESCR ALTA. Um produto de interpolímero que compreende: um primeiro interpolímero de etileno que compreende etileno e uma a-olefina que tem peso molecular médio ponderal (Mw) maior que 250.000 e uma densidade menor que 0,930 g/cm3, e um segundo interpolímero de etileno que compreende etileno e uma a-olefina em que o segundo interpolímero de etileno compreende um Mw menor que 70.000 e uma densidade maior que 0,930 g/cm3; e em que o produto de interpolímero compreende uma resistência a fraturas sob tensão ambiental (ESCR), medida de acordo com ASTM D1693, Condição B, 10% de IGEPAL CO-630, maior que 90 horas. O produto de interpolímero pode ser fabricado em um processo de polimerização em solução contínua utilizando pelo menos dois reatores empregando pelo menos uma formulação de catalisador de único sítio e pelo menos uma formulação de catalisador heterogêneo.
