PROBLEM TO BE SOLVED: To provide a filmy material of an insoluble and infusible substituted polyacetylene, having high heat resistance and solvent resistance, and further to provide a method for producing the filmy material. SOLUTION: This filmy material is the one made of the substituted polyacetylene having a phenyl group and an aromatic group. The method for producing the filmy material of the substituted polyacetylene having the phenyl group and the aromatic group comprises obtaining the filmy material from a solution- and melt-moldable polymer, and allowing a trialkylsilyl group to be eliminated from the resultant product. The separation method comprises using the filmy material. |
