PURPOSE:To obtain a high-MW or solvent-insoluble substituted polyacetylene of a high degree of polymerization, useful as an electroconductive or photoconductive material or for various optical uses, mainly consisting of structural units of specified formulas. CONSTITUTION:A substituted polyacetylene which is solvent-insoluble or has a weight-average MW>=50,000, mainly consisting of structural units of formula I (wherein X is C or N, and when X is C, it must have a substituent Y, while when X is N, it has no substituent Y, said substituent Y being an electron-with drawing or electron-donating group, Z<1>-Z<4> are each H, an electron-withdrawing or electron-donating group, and R is H, alkyl or cycloalkyl). This polymer can be obtained by polymerizing a monomer of formula II (wherein X, Y, Z<1>-Z<4> and R are as defined above) by using a specified catalyst, for example, a compound of formula III (wherein COD is cyclooctadienyl and bipy is bipyridyl). This polymer is moldable into a film and the concentration of radicals in the polymer can be increased by heating. By, e.g. adding a dopant to it, it can be used in various uses as an electroconductive or photoconductive polymer.
