Polyacetylene is a family of polymers with the chemical formula (C2H2)x, consisting of a chain of alternating double bonds between carbon atoms. It is a hydrocarbon polymer formed from the monomer acetylene (C2H2).The term "polyacetylene" refers to a class of polymers that have a repeating unit of CHCH in their backbone structure, which are formed by the copolymerization of acetylene. Polyacetylene is a semi-conductive polymer and has potential applications in the field of electronics and photonics.There are two primary forms of polyacetylene: cis-polyacetylene and trans-polyacetylene, which differ in the orientation of the double bonds along the polymer chain.
