The heating is done at 150-190 degrees C and further heating is done at 170-190 degrees C. The polyhydrazide is obtained for 1-3 hours. A neutralization step is carried out in a basic solution to eliminate an etching effect. Preferred Ratio: A molecular ratio of the aromatic and/or heteroaromatic prim. amine to polytriazole is 1:1 and/or the molecular ratio of the aromatic and/or heteroaromatic prim. amine is 0.4 mol/150 g to the amount of polyphosphoric acid. A molar ratio of N/C of nitrogen to carbon is 0.168-0.175. A molar ratio S/C of sulfur to carbon is 0.018-0.4. Preferred Property: The molecular weight is greater than or equal to 105 g/mol. The intrinsic viscosity, measured in dimethylsulfoxide, is 1-5 dL/g. EXAMPLE - A 4,4'-diphenylether-dicarboxylic acid (DPE) and hydrazinesulfate (HS) were reacted for 1 hour at 160 degrees C, then the reaction temperature was increased to 180 degrees C. Then, 4-aminobenzenesulfonic acid was added to the reaction vessel. A molar ratio of polyhydrazide, formed in situ, to 4-aminobenzenesulfonic acid of 1:1 was used. The reactive medium was put into lukewarm water containing 5 wt.%/vol. sodium hydroxide solution to precipitate the polymer. The pH-value of the polymer suspension was controlled. A dark blue fiber was obtained, which was first cleaned in distilled water and dried in a vacuum furnace for 48 hours at 100 degrees C. The ratio nitrogen/carbon of the synthesized polymer was 0.174 and the ratio sulfur/carbon was 0.058. The average molecular weight was 560,000. The conversion of oxadiazole groups into triazole rings was at 88%. The polymer (1 g) was dissolved in N-methyl-2-pyrrolidone (14 g). The solution was stirred for 4 hours and poured on a glass plate. The sulfonated poly(4-aryl-1,2,4-triazole)-membrane was dried at 80 degrees C for 24 hours in vacuum furnace. The thickness of the dark blue membrane was 90 mu m.
