Beschreibung
Zusammenfassung:	A polyethylene-based composition may include an ethylene-based copolymer produced from ethylene and one or more C3-C10 alpha olefin comonomers, wherein the ethylene-based copolymer has: a density ranging from 945 kg/m3 to 961 kg/m3 according to ASTM D792, a melt flow rate (MFR2) ranging from 0.5 g/10 min to 3.0 g/10 min according to ASTM D1238 at 190°C/2.16 kg, a molecular weight distribution (Mw/Mn) ranging from 3 to 25, and a stress exponent (SEx) ranging from 1.0 to 1.8. La présente invention concerne une composition à base de polyéthylène pouvant comprendre un copolymère à base d'éthylène produit à partir d'éthylène et un ou plusieurs comonomères d'alpha-oléfine en C3-C10, le copolymère à base d'éthylène ayant : une densité allant de 945 kg/m3 à 961 kg/m3 selon la norme ASTM D792, un indice de fluidité à chaud (MFR2) allant de 0,5 g/10 min à 3,0 g/10 min selon la norme ASTM D1238 à 190 °C/2,16 kg, une distribution de poids moléculaire (Mw/Mn) allant de 3 à 25, et un exposant de contrainte (SEx) allant de 1,0 à 1,8.
