Carrier bags are often made from poly(ethene). Poly(ethene) is made from small molecules of ethene, C2H4\mathrm{C_{2}H_{4}}C2H4.
Give the name for the small molecules, such as ethene, that join together to make a polymer.
Name the type of polymerisation that turns ethene into poly(ethene).
Give the feature of an ethene molecule that allows it to form a polymer.
Describe what happens to the ethene molecules when they form poly(ethene).
Name the polymer made from propene.
