A fluorine-containing carboxylic acid represented by the following formula or an acid chloride, an acid anhydride, or an ester derived therefrom, preferably an acid chloride, is added thereto, and the mixture is further reacted for 0.5 to 3 hours. If necessary, about 0.9 to 1.2 moles of a salt hydrogenated scavenger are added to accelerate the polymerization reaction, and the polymer produced at room temperature and reaction time of 0° for 5 to 10 hours is the polyamide of the present invention. Most of the imide polymer (e.g. 50-100%
) is converted into the ring-closing precursor amide amic acid unit/C0NH-R→1+NH-CO-A r \COOH, resulting in a so-called polyamide amic acid. The organic polar solvent used in this first step includes dialkylcarboxylic acid amides, N-methylpyrrolidone, heterocyclic compounds such as tetrahydrothiophene-1,1-dioxide, and phenols such as cresol and xylenol. , N-methylpyrrolidone and N-N-dimethylacetamide are preferred, and the salt hydrogen scavenger optionally added to the first step is an aliphatic scavenger such as trimethylamine, triethylamine, tripropylamine, tributylamine. 3

It is carried out by heating to 50-400°C, preferably 100-250°C. At this time, it is more effective to use an azeotropic solvent useful for water removal, such as benzene, toluene, xylene, chlorobenzene, etc. in combination. In-phase thermal ring closure is performed by first isolating a polyamide amic acid polymer from the polyamide amic acid solution obtained in the first step and heat-treating it in a solid phase state. As the precipitant for isolating the polyamide/amic acid polymer, a liquid that is miscible with the reaction mixture solvent but in which the polyamide/amic acid itself is insoluble, such as water or methanol, is employed. Thermal ring closure is usually performed at 150-350°C10.5-5
The conditions are set to ensure the desired ring closure rate and melting fluidity from the 0 hour condition.

Care must be taken because the polymer itself tends to form a three-dimensional crosslinked structure and significantly reduce fluidity when melted.
