The effects of High Performance Caking(HPC)addition on the thermoplasticity of coking coal have been investigated with ^1H-NMR relaxation measurements. Fractional intensity, f(L1), and molecular mobility, T2(L1), of mobile component, L1, increased with HPC addition at lower temperature range. At higher temperature range, that is thermoplastic temperature range, f(L1) and T2(L1) shows almost the same value as those for original coal blends. These results indicate that the HPC can be added as a substitution for coking coals.
