Abstract
COPOLÍMERO DE POLIETILENO DE BAIXA DENSIDADE LINEAR BIMODAL, E, ARTIGO FABRICADO. São fornecidos copolímeros de polietileno de baixa densidade linear bimodais (copolímeros de B-LLDPE) que têm uma combinação de propriedades melhoradas compreendendo pelo menos uma característica de processabilidade similar à de um ZN-LLDPE monomodal não misturado e uma propriedade de impacto de dardos similar ou melhor à de um MCN-LLDPE monomodal não misturado. Para os vários aspectos, o copolímero de B-LLDPE tem uma densidade de 0,8900 a 0,9300 g/cm3; um índice de fusão (I2) de 0,1 g/10 min a 5 g/10 min; um Mz de 600.000 a 1.900.000 g/mol; e um SHI de 5,35 a 75 Eta*(1,0)/Eta*(100). O copolímero de B-LLDPE pode ser adicionalmente caracterizado por uma primeira razão de fluidez (I21/I2) de 32 a 140 e uma primeira razão de peso molecular (Mz/Mw) de 4,5 a 11.
