- 4.7 Organic chemistry
- 4.7.3 Synthetic and naturally occuring polymers
- 4.7.3.2 Condensation polymerisation (HT only)
- Condensation polymerisation involves monomers with two functional groups. When these types of monomers react they join together, usually losing small molecules such as water, and so the reactions are called condensation reactions.
- The simplest polymers are produced from two different monomers with two of the same functional groups on each monomer. For example, the polyester formed from ethane diol and hexanedioic acid.
- Students should be able to explain the basic principles of condensation polymerisation by reference to the functional groups in the monomers and the repeating units in the polymers.
- 4.7.3.1 Addition polymerisation
- Alkenes can be used to make polymers such as poly(ethene) and poly(propene) by addition polymerisation.
- In addition polymerisation reactions, many small molecules (monomers) join together to form very large molecules (polymers).
- In addition polymers the repeating unit has the same atoms as the monomer because no other molecule is formed in the reaction.
- Students should be able to: recognise addition polymers and monomers from diagrams in the forms shown and from the presence of the functional group C=C in the monomers.

- Polymers
- 9.18C Describe: how ethene molecules can combine together in a polymerisation reaction; that the addition polymer formed is called poly(ethene)
- 9.19C Describe how other addition polymers can be made by combining together other monomer molecules containing C=C, to include poly(propene), poly(chloroethene) (PVC) and poly(tetrafluoroethene) (PTFE)
- 9.20C Deduce the structure of a monomer from the structure of an addition polymer and vice versa
- 9.22C Explain: why polyesters are condensation polymers; how a polyester is formed when a monomer molecule containing two carboxylic acid groups is reacted with a monomer molecule containing two alcohol groups; how a molecule of water is formed each time…
