Mutual diffusion coefficients for poly(2-ethyl hexyl methacrylate) + acetate ester(methyl acetate, ethyl acetate and propyl acetae) systems, poly(2-ethyl hexyl methacrylate) + ketone(acetone, methyl ethyl ketone and methyl propyl ketone) systems, poly(n-hexyl methacrylate) + acetate ester systems and poly(n-hexyl methacrylate) + ketone systems were measured at 30-70℃ by using a sorption apparatus with a quartz spring and a gas chromatography techniqueIt was found that,for all systems measured, the mutual diffusion coefficients obtained increased with increasing temperature, concentration of solvent and decreased increasing molecular weight of solvent. In addition, the mutual diffusion coefficients were predicted by the modified free volume theory. The parameters required in the prediction model were estimated by applying a previous method based on the physical properties of solvent. The six model parameters were correlated with the molecular weight, M_1, molar volume, V_b, at the normal boiling point and cohesive energy, E_<coh>, at the normal boiling point of solvent. The correlation equations obtained could be expressed by a linear function of M_1, V_b or E_<coh>. The mutual diffusion coefficients were predicted using these correlation equations. The predicted results were in good agreement with the experimental data at average relative errors within 13%. These knowledge will be useful in developing a equipment to remove volatile organic solvents from acrylic polymer products

聚乙烯的互扩散系数（2-乙基己基甲基丙烯酸酯）+乙酸酯（乙酸甲酯、乙酸乙酯和乙酸丙酯）体系，聚（2-乙基己基甲基丙烯酸酯）+酮（丙酮、甲基乙基酮和甲基丙基酮）体系，聚（甲基丙烯酸正己酯）+乙酸酯体系和聚用石英弹簧吸附装置和气相色谱技术在30 - 70 ℃测定了甲基丙烯酸正己酯+酮体系，发现对所有测定的体系，所得互扩散系数随温度、溶剂浓度的升高而增大，随溶剂分子量的增加而减小。此外，用修正的自由体积理论预测了互扩散系数。在预测模型中所需的参数估计通过应用以前的方法的基础上的溶剂的物理性质。模型参数分别与溶剂的分子量M_1、标准沸点摩尔体积V_B和标准沸点内聚能E_相关。<coh>得到的相关方程可用M_1、V_B或E_的线性函数表示。<coh>利用这些相关方程预测了互扩散系数。预测结果与实验数据吻合较好，平均相对误差在13%以内。这些知识将有助于开发一种从丙烯酸聚合物产品中去除挥发性有机溶剂的设备
