ABSTRACT:
The present invention provides a process for producing a polyacetylene which is stable even in an atmosphere containing oxygen, by spreading onto the surface of water, which contains Ca-salt, a solution of a fatty acid series substance containing an acetylene group or diacetylene group dissolved in an organic solvent, removing the organic solvent by evaporation, gathering up molecules of the fatty acid series substance which remain on the water by means of a barrier, then irradiating the molecules in the state of a monomolecular film on the water surface by use of radiation, or by building up the molecules by means of Langmuir-Blodgett (LB) film method under a definite surface pressure.
