How is poly(ethene) formed?
Poly(ethene) is formed when several monomers of ethene (an alkene) are joined together. Ethene can take part in this type of reaction as it is has a double bond (it's unsaturated) which opens up to allow multiple monomers to form a chain. This reaction occurs when ethene is heated and put under pressure in the presence of a catalyst.
