Identify the type of polymer that forms from $\text{C2}$.

Draw one repeat unit of the polymer formed from $\text{C2}$.

As well as producing fuels, this process produces compounds suitable for use in the production of polymers. An example of such a compound is but-2-ene, $\text{CH}_3\text{CH}=\text{CHCH}_3$.

Draw the repeat unit of the polymer that is produced from but-2-ene.

Name the type of polymerisation that occurs during the production of the polymer in (ii).
