Dienes

Polymers made from diene monomers are usually quite flexible and are used as elastomers. This group includes natural rubber and related materials, as well as the large number of synthetic polymers made with diene monomers. Residual unsaturation in these polymers is often used to cross-link (vulcanize) the materials to improve their physical properties.
