Abstract
A process for the production of polyacetylene derivatives by which polyacetylene derivatives having an ability to discriminate asymmetry can be easily obtained in a few steps and in high yield and which is also advantageous in respects of economical efficiency, environmental problems, and so on. This process is characterized by polymerizing an acetylene derivative having a hydrophilic functional group in an aqueous solvent in the presence of a water-soluble transition metal complex catalyst and a base.
