Plastics When oil is cracked ethene is often made. Ethene is a very useful molecule as it is the starting material for making many plastics.
3
Plastics Plastics are huge molecules. They are usually made from chains of thousands of atoms. These long chains are called polymers
4
Plastics Polymers are made from joining thousands of small molecules called monomers together.
5
Plastics Ethene is a monomer that joins up to form poly(ethene). This reaction is called polymerisation
6
Plastics Different plastics can be made from different monomers.
