## Notes

Polysulphides are polymers characterised by the presence of monosulphide linkages in the polymer chain, for example, poly(phenylene sulphide). In polysulphides each sulphur atom is bound on both sides by carbon atoms, as opposed to the thioplasts of Chapter 40, which contain sulphur-sulphur linkages. Polysulphides are used in coatings and in moulded articles, for example, aircraft and automobile parts, pump impellers.
