Abstract

A polyethylene (PE) comprising:a) a first polyethylene fraction (PEI) being a copolymer of ethylene and one or more comonomers selected from the group consisting of Cs-Cs alpha olefins, andb) a second polyethylene fraction (PE2) being a copolymer of ethylene and one or more comonomers selected from the group consisting of Cs-Cs alpha olefins,wherein the second polyethylene fraction (PE2) has an intrinsic viscosity value (iV), determined according to ISO 1628-1:2021 and ISO 1628-3:2010, in decalin at 135 °C, and a total comonomer content value (Co), determined according to quantitative ¹³C-NMR spectroscopic analysis, that fulfil inequation (I): CoPE2−iVPE2≥Awherein the intrinsic viscosity (iV) is expressed in dL/g and the comonomer (Co) content is expressed in mol-%, andwherein A is 1.00.
