A COMPOUND OBTAINED BY REACTING A COMPOUND HAVING A CARBOHYDRAZIDE STRUCTURE WITH AN ACID OR A BASE

摘要

A method for producing a film which comprises an aromatic amide oxadiazole polymer containing an oxadiazole structure, the method comprising: immersing a film containing a carbohydrazide structure in a dehydration-cyclization agent solution bath at room temperature to produce a compound having an oxadiazole structure by dehydration-cyclization of the carbohydrazide structure, wherein the dehydration-cyclization agent solution consists of a base and solvent; and heat treating the film at a temperature 200°C to 500°C for several seconds to several minutes.
