| Abstract: | A new peak at 39.0 ppm in the 13C-NMR spectrum of polybutadiene (PBD) was discovered. This peak is assigned to the fouth trans peak (T4) of trans 1, 4-sequence marked with an asterisk as shown in Fig. 3 in the text.The occurrence of T4 carbon nuclei is strongly affected by their neighboring 1, 2-units. So long as both contents of trans 1, 4- and 1, 2-units reach their proper amount, the peak (T4) will appear in the 13C-NME spectrum of PBD. |
