New structures from the thermal rearrangement of polybutadiene revealed by 2D HSQC NMR

The thermal reactions of polybutadiene (PB) at 260 °C in inert atmosphere were followed by 1H and 13C NMR spectroscopy. Within 24 h of heating, the change in the intensities of some peaks and the appearance of new peaks of NMR spectra permits to follow the reactions occurring in polybutadiene. The s...
