Quick explanation

Draw repeating units and monomers for polyesters and polyamides

  • This point belongs to Polymers (A-level only), especially Polymerisation and polymer properties (A-level only).
  • You need to be able to draw repeating units and monomers for polyesters and polyamides.
  • The key ideas to know are polyamide, monomer, and polyester.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Why it matters

This objective helps connect Polymerisation and polymer properties (A-level only) to exam-style questions, flashcards, and revision notes for Polymers (A-level only).

Quick student answer

Which of the following is a correct repeating unit for the polyester formed from ethylene glycol and terephthalic acid?

Direct answer

A) -O-C₆H₄-CO-O-C₂H₄-

Key terms

  • Repeating unit: The smallest structural unit of a polymer that repeats to form the entire polymer chain.
  • Monomer: A small molecule that can join together with other monomers to form a polymer.

Common trap

Incorrectly identifying the repeating unit: Ensure that the repeating unit reflects the structure of the polymer formed, including all necessary linkages.
