Q
What is polymerisation?
A
Putting lots of monomers together to make large molecules called polymers. eg many ethene molecules put together to make polyethene.
2

Q
What are the pros and cons of using polymers?
A
Pros: Usually cheaper than things made from metal, recyclable.
Cons: Not biodegradable, prices will rise, made from alkenes, which comes from fossil fuels)
