Empirical relationships were obtained at temperatures 10--80 °C between density p and mass concentration C (wt%) of pullulan, which was used as a standard polymer in aqueous solutions containing two representative ionic liquids, l-butyl-3-methylimidamlium chloride and 1-ethyl-3-m.ethylimidaolimn acetate. Water content effect on p was also examined. Pullulan was successfully dissolved into these ionic liquids without degradation, confirmed by the recovered samples. This indicates that pullulan is a suitable standard for ionic liquid soluble polymers. The empirical relationships provide easy conversion of C to concentration c (g/cm^3), which is essential for systematic studies of properties of pullulan in ionic liquids.
