Abstract

Patente de Invenção: "MASSAS DE MOLDAGEM DE POLIETILENO COM RELAçãO DE RIGIDEZ AO ESCR E QUOTA DE INCHAçãO APERFEIçOADAS, PROCESSOS PARA A SUA PREPARAçãO E SUA APLICAçãO". A invenção refere-se a uma massa de moldagem de polietileno com distribuição da massa molar multimodal, que possui uma densidade total de <242> 0,940 g/cm^ 3^ e um MFI~ 190/5~ na faixa de 0,01 até 10 dg/min. A massa de moldagem de acordo com a invenção contém uma quantidade de 30 até 60%, em peso, de homopolímero de etileno A de baixo peso molecular, que possui um índice de viscosidade VZA na faixa de 40 até 150 cm^ 3^/g, uma quantidade de 30 até 65 em peso, de copolímero B de peso molecular elevado de etileno e uma outra olefina com 4 até 10 átomos de carbono, que possui um índice de viscosidade VZ~ B~ na faixa de 150 até 800 cm^ 3^/g e uma quantidade de 1 até 30%, em peso, de homopolímero de etileno C de peso molecular superelevado, que possui um índice de viscosidade VZc na faixa de 900 até 3000 cm^ 3^/g. A invenção refere-se também a um processo para preparar a massa de moldagem em um processo de três etapas e sua aplicação para a preparação de corpos ocos.
