CA 2511545

The invention relates to a polyethylene composition with multimodal molecular mass distribution, which is particularly suitable for the blow molding of L- ring drums having a volume in the range of from 50 to 250 dm3 (I). The composition has a density in the range of from 0.950 to 0.956 g/cm3 at 23 ~C and a MFR1gp/21.6 in the range from 1.5 to 3.5 dg/min. It comprises from 35 to 45 % by weight of a low-molecular-mass ethylene homopolymer A, from 34 to 44 % by weight of a high-molecular-mass copolymer B made from ethylene and from another 1-olefin having from 4 to 8 carbon atoms, and from 18 to 26 % by weight of an ultrahigh-molecular-mass ethylene copolymer C.

L'invention concerne une composition de polyéthylène présentant une distribution de la masse moléculaire multimode, qui convient particulièrement pour le moulage par soufflage de fûts de type L-ring dont le volume est compris entre 50 et 250 dm?3¿ (I). La composition de l'invention présente une densité comprise entre 0,950 et 0,956 g/cm?3¿ à 23 ·C, et un MFR¿1gp/21.6? compris entre 1,5 et 3,5 dg/min. Elle comprend 35 à 45 % en poids d'un homopolymère d'éthylène A de faible masse moléculaire; 34 à 44 % en poids d'un copolymère B de masse moléculaire élevée constitué d'éthylène et d'une autre 1-oléfine présentant 4 à 8 atomes de carbone; et 18 à 26 % en poids d'un copolymère d'éthylène C de masse moléculaire très élevée.
