Title (EN) POLYETHYLENE COMPOSITIONS AND FILMS PREPARED THEREFROM
(FR) COMPOSITIONS DE POLYÉTHYLÈNE ET FILMS PRÉPARÉS À PARTIR DE CELLES-CI
Abstract:
(EN) A polyethylene composition comprising from about 0.5 to about 20 wt% of alpha-olefin derived units other than ethylene-derived units, with the balance including ethylene-derived units, total internal unsaturations (Vy1+Vy2+T1) of from about 0.10 to about 0.40 per 1000 carbon atoms, an MI of from about 0.1 to about 6 g/10 min, an HLMI of from about 5.0 to about 40 g/10 min, a density of from about 0.890 to about 0.940 g/ml, a Tw1-Tw2 value of from about -25 to about -20°C, an Mw1/Mw2 value of from about 1.2 to about 2.0, an Mw/Mn of from about 4.5 to about 12, an Mz/Mw of from about 2.0 to about 3.0, an Mz/Mn of from about 7.0 to about 20, and a g'(vis) greater than 0.90.
(FR) L'invention concerne une composition de polyéthylène comprenant d'environ 0,5 à environ 20 % en poids de motifs dérivés d'alpha-oléfine autres que des motifs dérivés d'éthylène, le reste comprenant des motifs dérivés d'éthylène, des insaturations internes totales (Vy1 + Vy2 + T1) d'environ 0,10 à environ 0,40 pour 1000 atomes de carbone, un MI d'environ 0,1 à environ 6 g/10 min, un HLMI d'environ 5,0 à environ 40 g/10 min, une densité d'environ 0,890 à environ 0,940 g/ml, une valeur Tw1-Tw2 d'environ -25 à environ -20 °C, une valeur Mp1/Mp2 d'environ 1,2 à environ 2,0, un Mp/Mn d'environ 4,5 à environ 12, un Mz/Mw d'environ 2,0 à environ 3,0, un Mz/Mn d'environ 7,0 à environ 20, et un g (vis) supérieur à 0,90.
