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.
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.
