Formation of polythene
Videonummer 11932178
| Animation showing the formation of a long chain of the plastic polythene from molecules of ethene. Polythene (or polyethene or polyethylene) is the most commonly produced plastic. Polythene is produced by the polymerisation of molecules of ethene in the presence of a metal-based catalyst. The double bond linking the two carbon atoms (black) in ethene is broken, forming a new single bond (red) between the atoms. Polythene can be produced with a wide variety of chain lengths, side branches and densities, with each having different characteristics and consequently different uses. | |
