Abstract
Copolymers of N-vinylformamide (NVF) with acrylamide (AM), sodium acrylate (NA), and n-butyl acrylate (BA) have been prepared by free-radical polymerization in homogeneous solutions. Copolymer compositions were obtained by C-13 NMR. Reactivity ratios and microstructures of the resulting copolymers were determined. The reactivity ratios calculated by the method of Kelen-Tudos for NVF (M1)/AM (M2) were r1 = 0.046 and r2 = 0.51; for NVF (M1)/Na (M2), r1 = 0.22 and r2 = 0.52; and for NVF (M1)/BA (M2), r1 = 0.071 and r2 = 0.55. Microstructural data calculated by the method of Igarashi indicated that all three copolymer series exhibit high degrees of alternation.
