In today's world we make use of a wide range of different polymers. These polymers are often substitutes for traditional materials, but may have more useful properties.
(a)
Polymers can be either thermoplastic or thermosetting.
Name a thermoplastic polymer.
State which type of polymerisation produces thermoplastic polymers, explaining your answer in terms of the structure of the polymer.
