The thermal and mechanical properties of different cross‐linked and uncross‐linked polyethylene/wax blends were investigated over a period of time. This paper summarizes the results and observations. It was found that (i) both LLDPE and LDPE cross‐links in the presence of low dicumyl peroxide concentrations, while wax only grafts onto the polyethylene chains, (ii) polyethylene and wax have relatively good miscibility, (iii) both wax content and cross‐linking change the mechanical properties of polyethylene in one way or the other, (iv) the route of sample preparation has a marked influence on the thermal and mechanical properties of the blends, and (v) oxygen‐containing groups in oxidised wax apparently do not change the way in which the wax interacts with polyethylene.
