Abstract
An apparatus for producing a polyacetylene film by polymerizing acetylene gas in contact with Ziegler-Natta catalyst comprising in a vessel to be introduced with acetylene gas a rotatably driven film forming drum, a coating member for coating the Ziegler-Natta catalyst on the outer peripheral surface of the drum, a feeding roller driven reversely to the drum in rolling contact with the drum for drawing a polyacetylene film polymerized with the catalyst on the drum, a cleaning member for cleaning the drawn polyacetylene film, and a winding unit for winding the polyacetylene film. Thus, the polyacetylene film can be produced in high quality in a mass production.
