Many everyday plastics are addition polymers made by joining together large numbers of small, unsaturated molecules called monomers.
The table below shows the names and chemical structures of some common polymers and the monomers used to make them.
Complete the table by providing the missing chemical structures for (a) and (b), and the missing polymer name for (c).
