Patent

CA 2511358

The invention relates to a polyethylene composition with multimodal molecular mass distribution, which is particularly suitable for the blow moulding of canisters having a volume in the range of from 2 to 20 dm3 (I). The composition has a density in the range from 0.950 to 0.958 g/cm3 at 23 ~C and an MFR190/5 in the range of from 0.30 to 0.50 dg/min. It comprises from 40 to 50 % by weight of a low-molecular-mass ethylene homopolymer A, from 25 to 35 % by weight of a high-molecular-mass copolymer B made from ethylene and from another olefin having from 4 to 8 carbon atoms, and from 24 to 28 % by weight of an ultrahigh-molecular-mass ethylene copolymer C.

L'invention concerne une composition de polyéthylène présentant une distribution de masse moléculaire multimodale. Cette composition convient particulièrement au moulage par soufflage de réservoirs présentant un volume compris entre 2 et 20 dm?3¿ (I). Ladite composition présente une densité comprise entre 0,950 et 0,958 g/cm?3¿ à 23 ·C et une valeur MFR¿190/5? comprise entre 0,30 et 0,50 dg/min. Elle comprend entre 40 et 50 % en poids d'un homopolymère d'éthylène à faible masse moléculaire (A), entre 25 et 35 % en poids d'un copolymère à haute masse moléculaire (B) constitué d'éthylène et d'une autre oléfine renfermant entre 4 et 8 atomes de carbone, et entre 24 et 28 % en poids d'un copolymère d'éthylène à masse moléculaire ultra-élevée (C).
