Abstract

La présente invention concerne un polyéthène non réticulé dont la valeur de la différence normalisée entre son module de stockage G' et son module de perte G'', déterminée par mesure rhéologique dynamique, est continuellement inférieure à 0,5 sous des fréquences allant de 0,01 à 100 rad/s et à une température de 190 °C. Cette différence est de préférence sensiblement constante sous lesdites fréquences. On prépare de préférence ces polyéthènes en utilisant des catalyseurs métallocènes, et dans un mode de réalisation préférée ces catalyseurs sont à base de rac-éthylène bis(3-tri-isopropylsiloxy)indenyl zirconium dichloride ou de rac-éthylène bis(3-tert-butyldiméthylsiloxy)indenyl zirconium dichloride.
