Abstract
The present invention relates to an ethylene polymer comprising moieties according to Formula (IB): wherein R is a moiety comprising ≥1 and ≤10 carbon atoms; wherein Rand Rare each individually hydrogen or a moiety comprising ≥1 and ≤5 carbon atoms, Rand Rmay be the same or different; wherein the ethylene polymer has a molecular weight distribution of ≥3.0 and ≤40.0; the ethylene polymer has a melting temperature of ≥115° C.; the ethylene polymer has a density ≥935 and ≤960 kg/m3; the ethylene polymer is essentially free from chromium, hafnium, zirconium and tetrahydrofuran; for the fraction of the ethylene polymer having a molecular weight >100 kg/mol, the intrinsic viscosity of the ethylene polymer is related to the molecular weight according to the inequality: log I.V.<0.65*log M−3.10 Such polymers have high density, high purity and good processability, whilst maintaining barrier properties for oxygen and water vapour at a level similar to high-density polyethylenes produced via catalytic processes.
