— Examiner report, May/June 2025, 0654/43 Q7(a)(iv) (Cambridge)
Candidates had difficulty expressing their responses. There were many vague responses referring to variations of addition of monomers. The best responses recognised that condensation polymerisation resulted in more than one product, one of which is usually water.
— Examiner report, February/March 2022, 0654/42 Q5(f)(ii) (Cambridge)
The most able candidates often gave an answer in terms of condensation polymerisation producing a small molecule, or a named molecule such as water. Very few candidates were able to give a second difference in terms of the number of monomers involved in each reaction. Most responses showed very little understanding of this section of the syllabus.
