Popis:	Techniques for quantitative determination of N-vinylpyrrolidone and 2-methyl-5-vinylpyridine copolymers in aqueous solutions were developed. The spectrophotometric technique allowed the copolymer concentration in dilute solutions (0.8 – 1.2 mg/mL) to be determined even in the presence of the interfering additive merthiolate. The refractometric technique was simpler and allowed the copolymer concentration in concentrated solutions (> 1 mass%) to be determined.
