Abstract: The present invention relates to a pipe comprising an ethylene-based polymer, wherein the ethylene-based polymer: ? comprises ?0.10 mol % of units derived from 1-hexene, with regard to the total molar quantity of polymeric units of the ethylene-based polymer; ? has an Mw/Mn as determined in accordance with ASTM D6474 (2012) of ?2.5 and ?4.0, preferably of ?2.5 and ?3.4; ? has a density as determined in accordance with ASTM D792 (2008) of ?925 and ?945 kg/m3; and ? in the molecular weight range of log(Mw) between 4.0 and 5.5, has a comonomer branch content of between 2 and 15 comonomer-derived branches per 1000 carbon atoms in the polymer, as determined via 13C NMR. Such pipe provides a desirably high long-term strength, as demonstrated by its high strain hardening modulus, as well as desirably high impact strength, as demonstrated by its high Charpy impact strength. Further, such pipe may be compliant with the PE-RT requirements of ISO 22391-1 (2009).
