The solubility parameters of cellulose acrylate substituted degree 2.12 (CEA) have been calculated from the measured retention data by inverse gas chromatography at various temperatures. The weight fraction activity coefficients of the solvents at infinite dilution (Ω_1~∞), the Flory-Huggins thermodynamic interaction parameters between CEA and solvents (χ_(12)~∞), the excess molar heats of mixing (△H_1~S), the partial molar heats of mixing at infinite dilution (△H_1~∞), the solubility parameters of solvent (δ_1), and the solubility parameters of CEA (δ_2), were calculated at various temperatures. The δ_2 of the CEA was 17.32, 18.00,18.13,18.54,19.39 at 55, 60, 65, 70 and 75 ℃, respectively.
