• It produces a polymer and water as a by-product.
• Poly(ethene) is an example of a polymer formed by addition polymerisation.
• It forms polymers with amide linkages.

Identify the type of polymer involved

In condensation polymerisation, a small molecule like ___ is usually eliminated.

• Water

• water

• H2O

• h2o

Which of the following are examples of condensation polymers? (There may be more than one correct option)

• A
• B
• C
• D

Nylon and PET are examples of addition polymers.

Water is released during the formation of polyamides.

What is the key structural difference between addition and condensation polymerisation?

• Addition polymerisation eliminates a small molecule, while condensation does not.
• Addition polymerisation requires functional groups, while condensation does not.
• Condensation polymerisation eliminates a small molecule, while addition does not.
• Condensation polymerisation uses double bonds, while addition does not.
