Radical Copolymerization of N-Vinylpyrrolidone with Methyl Methacrylate and Styrene in the Presence of C-Phenyl-N-tert-butylnitrone

摘要

The effect of C-phenyl-N-tert-butylnitrone on the features of radical copolymerization of N-vinylpyrrolidone with methyl methacrylate and styrene was examined. Nitrone exerts virtually no effect on the relative activities of the comonomers. At the same time, C-phenyl-N-tert-butylnitrone as a potential source of nitroxyl radical makes it possible to prepare copolymers of N-vinylpyrrolidone with methyl methacrylate and styrene to high conversions without gel effect, to control the molecular-weight characteristics of the copolymers, and to prepare block copolymers.
