Quick check
Answer each question before opening the answer.
How does addition polymerisation work?
Many small monomers containing C=C double bonds join together to form one long polymer, with no other product.
Why is disposing of addition polymers a problem?
They are non-biodegradable (do not rot) and release toxic gases if burned.
