Thermoplastic properties of coal and coal with "High Performance Coking additive, HPC" are investigated by means of ^1H-NMR relaxation measurement from the viewpoints of molecular mobility. High temperature ^1H-NMR relaxation measurement enable to monitor the actual changes in progress of thermal transformation. The quantitative change of specimens can be evaluated by recording the hydrogen content of residual specimens, and qualitative variation of the specimen is able to detect as a change of the relaxation characteristics of signal. In this study, it is confirmed that ^1H-NMR re laxation measurement is the appropriate dynamic measurement technique to characterize the thermoplastic properties of coal. The results obtained from ^1H-NMR relaxation measurement demonstrated that the improvement of the thermoplasitic phenomenon of coal with HPC is evaluated both qualitatively and quantitatively by the variation of IHm and T2Hm. It is also investigated that the properties of HPC is affected with the feedstock of HPC.
