Coal extracts-solvent gel films are prepared by evaporation of N-methyl-2-pyrrolidinone (NMP) from coal extract solution in NMP. FT-IR mesurment was carried out to investigate the physical state of NMP in the gel films. A significant amount of NMP were found to form hydrogen bonds with coal in the gel film. Temperature dependence of viscoelasticity was investigated to clarify cross-linking structure of the gel.
