What is addition polymerisation?Show answer
Addition polymerisation joins alkene (or substituted alkene) monomers. The C=C double bond opens up and the carbons bond directly to neighbouring units, so no atoms are lost: every atom of the monomer ends up in the polymer. For ethene:
What is condensation polymerisation?Show answer
Condensation polymerisation joins monomers that each have two reactive functional groups, and a small molecule (usually water) is eliminated at each link. Two important examples:
