The present disclosure provides a low density polyethylene (LDPE) having (A) a density from 0.910 to 0.924 g/cm, determined according to ISO 1183 at 23&#xb0; C.; (B) an elongational hardening of at least 4.2, at 150&#xb0; C. at an elongational rate of 1 s; (C) a ratio Mw/Mn of at least 18, where (i) Mw is the weight average molar mass, measured by a MALLS detector coupled to a GPC, and (ii) Mn is the number average molar mass, measured by GPC (Gel Permeation Chromatography); and (D) a Mw of at least 230,000 g/mol. The present disclosure also provides an article of manufacture made from or containing (A) a substrate and (B) a coating layer made from or containing the disclosed LDPE. The present disclosure further provides a polymerization process occurring (A) in the presence of oxygen as the only radical initiating agent and (B) in the absence of solvents.
