PURPOSE:To obtain a polyacetylene showing electrical conductivity and non- linear optical effects, stable even in an oxygen-containing atmosphere, by immersing a substrate having hydrophilic surface in a nonaqueous organic solvent having dissolved a substance containing specific groups and polymerizing the substance by irradiating radiation. CONSTITUTION:A substrate having hydrophilic surface is immersed in a nonaqueous organic solvent having dissolved a substance containing acetylene group (CidenticalC) group and chlorosilane group (-SiCl), the substance containing acetylene group and chlorosilane group is chemically adsorbed on the surface of the substrate, the substrate is irradiated with radiation such as X-ray, electron beam or gamma rays and the substance is polymerized to produce a polyacetylene. A straight-chain ultra-high-molecular weight polyacetylene having several mm-several cm length by continuation of conjugated system can be produced by this method. The method is effective for producing devices using non-linear optical effects and organic superconducting substance requiring no cooling.
