Condensation Polymers – Lesson & Worksheet – Unit 4 – IGCSE Chemistry
Polyester Formation, Repeat Units, and Biopolyesters (Triple Only)

This Synapse Science resource introduces condensation polymerisation for Triple Science students. It explains how a dicarboxylic acid reacts with a diol to form a polyester, with water as a byproduct. Students learn how to draw structural and displayed formulae for repeat units, including the reaction between ethanedioic acid and ethanediol.

The lesson also explores biopolyesters, their environmental benefits, and common applications.

TOPICS COVERED – SPECIFICATION POINTS

  • 4.48C: Know that condensation polymerisation, in which a dicarboxylic acid reacts with a diol, produces a polyester and water
  • 4.49C: Understand how to write the structural and displayed formula of a polyester, showing the repeat unit, given the formulae of the monomers from which it is formed (e.g. ethanedioic acid and ethanediol)
  • 4.50C: Know that some polyesters, known as biopolyesters, are biodegradable:contentReference[oaicite:0]{index=0}

WHAT’S INCLUDED

  • Editable PowerPoint lesson explaining condensation vs addition polymerisation
  • Step-by-step diagram of polyester formation and ester link creation
  • Printable worksheet with naming, drawing, and environmental tasks
  • Real-world application: biopolyesters like PLA and their uses in packaging

KEY FEATURES

  • Strong visual support for identifying functional groups and forming repeat units
  • Practice drawing structural and displayed formulae
  • Biopolyester examples linked to sustainability and decomposition
  • Triple-only content made accessible and exam-aligned
  • Consistent Synapse Science format for seamless delivery
