ABSTRACT OF THE DISCLOSURE POLYACETYLENE PRODUCTION This invention relates to a process for producing an oriented, crystalline poly(acetylene) (III) in film or fibrillar form by solvent casting a film from a solution of a polymer of the general formula (V) derived from a precursor monomer (IV), and transforming the pre-cast film of polymer (V) under tension or in a stress field into the poly(acetylene) (III), The transformation is carried out at a temperature between 20 and 200°C under reduced pressure over a duration of between 1 and 100 hours in an atmosphere inert to the precursor polymer (V) film and to the poly(acetylene) (III). Poly(acetylenes) are conducting polymers and find use in solid state batteries, field effect transistors and the like.
