WebConducting polymers (e.g. polyacetylene ): polyacetylene contains alternating double and single bonds. When a double bond forms, p orbitals overlap sideways. As this happens along that whole chain, all the p orbitals overlap to create a delocalised system of electrons. This means that the polymer can conduct electricity.
