Practise recognising polyester formation as condensation polymerisation and naming water as the small molecule produced.

Exam points

name the reaction between a dicarboxylic acid and a diol as condensation polymerisation
identify water or H2O as the small molecule formed alongside the polyester

[Maximum number: 1]

Ethanol, $\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}$ , can be manufactured from ethene and steam using a phosphoric acid catalyst.
