Abstract

"massa de moldar de polietileno, apropriada como material para tubos com excepcionais propriedades de processamento". a invenção refere-se a uma massa de moldar polimérica de um primeiro polímero de etileno (a) e um segundo polímero de etileno (b), que é particularmente apropriada para a produção de tubos de paredes grossas, de grande calibre. a massa de moldar contém uma quantidade na faixa de 55 a 75% em peso de primeiro polímero de etileno (a) e uma quantidade na faixa de 25 a 45% em peso de segundo polímero de etileno (b), respectivamente, com relação ao peso total da massa de moldar, sendo que o primeiro polímero de etileno (a) representa um copolímero de etileno com uma 1-olefina, com um número total de átomos de c na faixa de 4 a 10, como comonômero, e com uma fração de comonômero de 0,2 a 5% em peso, com relação ao peso do primeiro polímero de etileno (a), e uma ampla distribuição de massa molar bimodal e sendo que o segundo polímero de etileno (b) representa um copolímero de etileno e uma 1-olefina, com 4 a 10 átomos de c, que possui uma distribuição de massa molar bimodal, que é diferente da massa do primeiro polímero de etileno (a). a invenção refere-se também a um tubo altamente resistente dessa massa de moldar e ao uso do mesmo para transporte de gás ou água.
