Low-density polythene: It has a density range of 0.910–0.940 g/cm3 and is prepared by the free-radical polymerization of ethane. The reaction is carried out at a temperature of 350 K to 570 K under the pressure of 1000 to 2000 atmospheres in the presence of a catalyst, dioxygen (in traces) or a peroxide initiator.
