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.
