Animation showing the a long chain of the plastic polythene (or polyethene or polyethylene). Polythene is the most commonly produced plastic. Polythene is produced by the polymerisation of molecules of ethene (C2H4) in the presence of a metal-based catalyst. Polythene can be produced with a wide variety of chain lengths, side branches and densities, with each having different characteristics and consequently different uses. | |
