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.
