Abstract

Radical copolymerization of coumarin with N-vinylamides (N-vinylpyrrolidone, N-vinylformamide, and N-methyl-N-vinylacetamide) initiated by 2,2′-azobisisobutyronitrile in bulk at 65°C has been studied. The comonomer reactivity ratios for the monomer pairs N-vinylformamide/coumarin (r₁ = 0.22±0.03, r₂ = 0) and N-methyl-N-vinylacetamide/coumarin (r₁ = 0.08±0.01, r₂ = 0) have been determined. Water-soluble copolymers of N-vinylamides with salts of oxycinnamic acid have been synthesized via alkaline hydrolysis of the obtained coumarin copolymers.

香豆素与 N-乙烯基酰胺的自由基共聚物散体

研究了香豆素与 N-乙烯基酰胺（N-乙烯基吡咯烷酮、N-乙烯基甲酰胺和 N-甲基-N-乙烯基乙酰胺）在 65°C 下由 2,2′-偶氮二异丁腈大量引发的辐射共聚。测定了单体对 N-乙烯基甲酰胺/香豆素（r1 = 0.22±0.03，r2 = 0）和 N-甲基-N-乙烯基乙酰胺/香豆素（r1 = 0.08±0.01，r2 = 0）的共聚单体反应比。通过碱性水解所获得的香豆素共聚物，合成了 N-乙烯酰胺与氧肉桂酸盐的水溶性共聚物。

期刊介绍： Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
