摘要：

C-13 NMR chemical shift assignments of comonomer sequences in an ethylene-propylene-1-butene terpolymer were obtained from mainly C-13 two dimensional INADEQUATE NMR experiment and the calculated chemical shifts on the basis of the C-13 NMR gamma-effect. By tracing carbon-carbon connectivities in the 2D INADEQUATE spectrum, two kinds of peaks, which were not separated in the 1D-INEPT spectrum, were assigned clearly. In addition, the chemical shift differences among comonomer sequences longer than tetrad were predicted by chemical shift calculation. Further, the conformational states of the side chain in the 1-butene unit were evaluated through the chemical shift calculation.
