Chemistry Topic Practice
Addition Polymerisation | GCSE Chemistry Practice
Addition polymers are formed when many small monomers join together to form large chains.
What happens to the double bond in an alkene during polymerisation?
What is Addition Polymerisation | Practice?
"A reaction where many small molecules (monomers) join together to form a very large molecule (polymer)."
Making Plastics
Monomers: Small molecules with double bonds (e.g. ethene).
Polymers: Long chains of repeating units (e.g. poly(ethene)).
The double bond opens up to connect to the next monomer.
The mass of the polymer equals the mass of the monomers used.
Exam Tip
Structure Tip: When drawing a polymer repeating unit, always draw square brackets and an "n" outside.
