    Abstract: The method for the production of a whole aromatic polyamide polymer of formula (III) (x = 0.05 - 0.5; y = 0-0.5) is characterized by polycondensing an aromatic diamine with an aromatic dibasic acid chloride in the polymerization solvent obtd. by dissolving an alkali metal salt into a tertiary amide solvent, and adding an aromatic tertiary amine as a reaction accelerator into the mixed solvent. The aromatic diame is pref. 3,5-diaminobenzophenone of formula (I) or a mixt. of (I) and methaphenylene diamine. The dibasic acid chloride is pref. isophthaloyl chloride, the alkali metal salt is lithium chloride or calcium chloride, and the tertiary amine is pref. pyridine, picoline or quinoline. The polyamide polymer is used in the mfr. of a heat-resistant transparent film for a circuit board, an insulating plate and a transparent protecting plate.
