The proposed method for determining the content of polyaniline in composite polymeric material consists in dissolving the material sample in N-methylpyrolidone for 3 ... 8 hours, adding ascorbic acid solution to the material solution in order to reduce polyaniline as leukoemeraldine, mixing the solution for 5 ... 15 hours if the material is not dissolved in N-methylpyrolidone, filtering the solution in order to remove disperse particles, analyzing the electronic-band absorption spectrum of the solution by using a quartz cuvette, and determining the content of polyaniline by the analysis results. The proposed method is distinctive by its enhanced accuracy.
