Summary Radical copolymerization of 2-(N,N-dimethyl)aminoethyl methacrylate (1) and acrylonitrile (2) initiated by 2,2′-azobis(2-methylpropionitrile) was carried out. The sequence distributions of the copolymers were investigated by 13C NMR spectroscopy. A terminal model was used to interpret the propagation process in the copolymerization. The monomer reactivity ratios in the bulk copolymerization at 45°C were evaluated as r1=1.06 and r2=0.07. Radical reactivity indices and frontier electron densities for 1 and 2 were calculated.
