Chromatographic methods of analysis of the products of the radical copolymerization of random copolymers of N-vinyl-2-pyrrolidone and 6-crotonoyl aminohexanoic acid are developed and molecular characteristics of the copolymers are determined. A method is proposed for the purification of the obtained carboxylated water-soluble copolymers of monomeric hydrophobic acid impurities by low-pressure gel-permeation chromatography.
