Virtually uncrosslinked polyacetylenes in film form are prepared by polymerization of acetylene using a liquid catalyst system consisting of an organicaluminum compound and a titanate in the form of a solution in a viscous inert liquid on a substrate to which the catalyst solution is applied, by a process in which, after the polymerization, the polymer is treated with a strong reducing agent which is inert to the organoaluminum catalyst component, the polymer is, if desired, oriented and is freed from residual catalyst and reducing agent by washing with a liquid, doped with a strong electron acceptor or electron donor in a conventional manner to increase the conductivity and dried, and the materials thus obtained are, if desired, covered with a layer or sheath of nonconductive material.
