• What are the key points about polymers and addition polymerisation?

  • Plastics are polymers.
  • Polymers consist of long chains of monomers.
  • Identify and name monomers, polymers, and repeating units.
  • Addition polymerisation creates polymers from monomers.
  • Proteins are natural polymers.
