Abstract

A method for producing a polyacetylene film by introducing acetylene gas into a vessel for storing Ziegler-Natta catalyst to polymerize the acetylene gas with the catalyst which comprises a film forming projecting flat section having a film forming flat surface projected from the surface of the Ziegler-Natta catalyst stored in the bottom of the vessel, thereby coating the Ziegler-Natta catalyst on the inner surface of the side wall of the vessel and the film forming flat surface. Thus, the acetylene gas introduced into the vessel is polymerized with the catalyst to produce the polyacetylene film. In this manner, the polyacetylene film having a constant thickness of high quality can be produced with the Ziegler-Natta catalyst of the suitable amount by providing the film forming flat surface even in the bottom of the vessel, thereby improving the production efficiency.
