摘要：
C-13 Nuclear magnetic resonance (NMR) spectra of atactic and syndiotactic-rich poly(methacrylonitrile) (PMAN) were determined. In addition, 2D (H-1-C-13 COSY(b))) NMR spectra of alpha-methyl and methylene regions of atactic PMAN were measured. Values of tetrads and pentads were calculated from triads obtained from alpha-methyl carbon absorptions of the samples. By comparing calculated values with the observed ones, and by taking 2D NMR spectra into consideration, both alpha-methyl carbon and proton absorptions were assigned by pentads, and methylene carbon absorptions by tetrads (partly by hexads).
