📐 Addition Polymerisation of Ethene

Diagram showing ethene monomers joining to form poly(ethene) chain through addition polymerisation, with double bonds opening to form single bonds in the chain

Figure 1: In addition polymerisation, many alkene monomers join together. The C=C double bond in each monomer opens up to form a single bond in the polymer chain. No other product is formed.
