Radical precipitative copolymerization of N-vinylformamide with acrylic and methacrylic acids in isopropanol at 60°C, with azobisisobutyric acid dinitrile as initiator, was studied. The conditional values of the relative reactivities were found: r 1 = 0.068 ± 0.008 and r 2 = 1.638 ± 0.025 for the N-vinylformamide-methacrylic acid copolymer and r 1 = 0.15 ± 0.03 and r 2 = 0.19 ± 0.09 for the N-vinylformamide-acrylic acid copolymer.
