The quantitative definition of <i>N</i>-vinylpyrrolidone and 2-methyl-5-vinylpyridine units ratio in the copolymers by UV-spectrophotometry

The quantitative definition of <i>N</i>-vinylpyrrolidone and 2-methyl-5-vinylpyridine units ratio in the copolymers by UV-spectrophotometry

The quantitative definition method of N-vinylpyrrolidone and 2-methyl-5-vinylpyridine ratio units in the copolymers using UV-spectrophotometry was developed. Copolymers were prepared by radical copolymerization using azo-bisisobutiric dinitrile as the initiator. On the basе of experimental results a...
