Abstract

New cross-linked copolymer with molecular imprints of 4-nitrophenol have been synthesized by the radical polymerization of cyclic N-vinyl amides and ethylene glycol dimethacrylate. Sorption characteristics of the obtained polymers depend on the nature of the functional monomer, ratio of components in the prepolymerization mixture, pH of solution, and temperature. It has been established that N-vinylpyrrolidone-based copolymers provide higher selectivity of 4-nitrophenol extraction than N-vinylcaprolactam-based products.
