| 摘 要： | 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 frac-tion activity coefficients of the solvents at infinite dilution(Ω1∞),the Flory-Huggins thermodynamic in-teraction parameters between CEA and solvents(χ 1∞2),the excess molar heats of mixing(△H1s),the par-tial molar heats of mixing at infinite dilution(△H1∞),the solubility parameters of solvent(δ1),and the solubility parameters of CEA(δ2),were calculated at various temperatures. The δ2 of the CEA was 17.32,18.00,18.13,18.54,19.39 at 55,60,65,70 and 75℃,respectively.

| Abstract: | 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 (Θ
1
∞
), the Flory-Huggins thermodynamic interaction parameters between CEA and solvents (χ
12
∞
), the excess molar heats of mixing (ΔH
1
s
), the partial molar heats of mixing at infinite dilution (ΔH
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°C, respectively.
