SYNTHESIS OF POLY[2-(N, N-DIMETHYL)AMINOETHYL METHACRYLATE-CO-ACRYLONITRILE]

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 i nvestigated by C-13 NMR spectroscopy. A terminal model was used to int erpret the propagation process in the copolymerization. The monomer re activity ratios in the bulk copolymerization at 45 degrees C were eval uated as r(1) = 1.06 and r(2) = 0.07. Radical reactivity indices and f rontier electron densities for 1 and 2 were calculated.
