Abstract

composições de polietileno de alta densidade e bimodal, e, artigo moldado. trata-se das composições de polietileno bimodal de alta densidade podem alcançar um equilíbrio melhorado de resistência à fissuração por estresse e processabilidade selecionando os componentes de maior peso molecular e de menor peso molecular, de modo que (1) o componente de maior peso molecular tenha uma distribuição de peso molecular abaixo de 4, (2) o menor o componente de peso molecular tenha uma densidade complementar de pelo menos 0,976 g/cm3, e (3) o copolímero bimodal geral tenha uma distribuição de peso molecular relativamente ampla. esta combinação de propriedades pode fornecer melhor equilíbrio entre resistência à fissuração por estresse e processabilidade.
