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.

Different polymers are created all the time so that the demands of … Polymers which are crystalline are usually opaque or translucent. As a polymer becomes less polycrystalline, it becomes more transparent, whilst an amorphous polymer is usually transparent. See more In some polymers, such as polyethene, the chains are folded up. When they are stretched, the chains unravel, stretching without breaking. When the stress ceases, … See more Polymer chains may be linked together, causing the polymer to become stiffer. An example is rubber, which, when heated with sulfur, undergoes a process known … See more When a polymer is stretched, the chains become parallel, and amorphous areas may become crystalline.
