Abstract
The present invention provides a process for producing a polyacetylene. In the present process for producing a polyacetylene, acetylene is polymerized with a Ziegler-Natta catalyst consisting of a trialkylaluminum and an alkyl titanate, wherein there is used, as the trialkylaluminum, a trialkylaluminum having an alkyl group of 6 or more carbon atoms, or, as the alkyl titanate, an alkyl titanate having an alkyl group of 6 or more carbon atoms. The polyacetylene obtained according to the present invention is superior in mechanical properties, particularly stretchability.
