Exam points

  • Deduce polyester repeat units from diols and dicarboxylic acids, checking ester links and continuation bonds.
  • Work backwards from a repeat unit to the two monomers, allowing displayed, structural or skeletal formulae.
  • Compare condensation polymerisation with addition polymerisation using small-molecule loss and atom economy.
