Abstract

"PROCESSO PARA A POLIMERIZAçãO DE ETILENO E UMA QUANTIDADE PEQUENA DE UM DIENO". Revelado é um processo de polimerização utilizando um nível baixo de dieno para controlar a razão do índice de fusão do produto de polímero independentemente do índice de fusão e densidade. O processo da invenção produz polímeros com processabilidade acentuada. Mais especificamente o processo produz polímeros baseados em etilaeno, preparados em processo de polimerização de fase gasosa utilizando catalisadores de polimerização de metaloceno de ligante volumoso, tendo comportamento de intensidade de fusão e adelgaçamento de cisalhamento acentuado."PROCESS FOR THE POLYMERIZATION OF ETHYLENE AND A SMALL AMOUNT OF A DIENO". Revealed is a polymerization process using a low level of diene to control the melt index ratio of the polymer product regardless of the melt index and density. The process of the invention produces polymers with marked processability. More specifically, the process produces polymers based on ethylene, prepared in a gas phase polymerization process using bulky binder metallocene polymerization catalysts, with a high melting intensity and shear thinning behavior.
