Abstract

La présente divulgation concerne des compositions d’interpolymère d’éthylène et des pellicules préparées à partir de ces dernières. Plus précisément, la présente concerne des produits d’interpolymère d’éthylène qui ont un facteur de ramification de chaîne longue (LCBF) sans dimension plus grand ou égal à 0,001, un métal catalytique résiduaire de 0,03 à 5 ppm de hafnium et un rapport d’insaturation (UR) de -0,40 à 0,06, l’UR étant défini par la relation suivante : UR = (SCU-TU)/TU, SCU étant la quantité d’une insaturation de chaîne latérale par 100 carbones et TU étant la quantité d’une insaturation de terminaison par 100 carbones dans le produit d’interpolymère d’éthylène. Les produits d’interpolymère d’éthylène décrits ont un indice de fluidité d’environ 0,3 à environ 500 dg/min, une densité d’environ 0,855 à environ 0,975 g/cm3, une polydispersité Mw/Mn d’environ 1,7 à environ 25 et un indice d’étendue de la distribution de composition d’environ 1 % à 98 %.
