【摘要】 对于处理含聚合物体系的化工过程，描述聚合物体系相平衡行为的数据具有非常重要的意义。聚合物溶液汽–液平衡数据库的内容涉及聚合物溶液汽–液平衡的主要数据类型，收集了1989年之前在关于聚合物的22种主要期刊上发表的原始文献，覆盖了约1500种聚合物和240种溶剂构成的聚合物溶液体系。为了提高数据的可使用性，本数据库对原始数据进行了规范化和使用便利化加工。在数据的规范化加工中，将典型的多种表达形式的聚合物溶液无限稀释数据和汽–液平衡数据加工为考虑汽相非理想性的溶剂无限稀释活度系数和溶剂活度。在数据的使用便利化加工中，将UNIQUAC活度系数模型推广应用于聚合物溶液汽–液平衡数据的关联，数据库提供经过处理的、便于使用的数据和关联方程参数。更多还原

【Abstract】 Data in the field of phase equilibrium of polymer solution play an important role in describing the phase behavior of polymer-containing systems. The polymer solution vapor-liquid equilibrium database collected the vapor-liquid equilibrium data and the solvent infinite dilution experimental data from 22 periodicals published by the end of 1989, covering the polymer solution systems composed of 1500 polymers and 240 solvents. The data were standardized and optimized for maximal applicability. The solvent infinite dilution data and the vapor-liquid equilibrium data were processed into solvent weight fraction activity coefficients at infinite dilution and solvent activities with vapor phase nonideality corrected. Furthermore, the UNIQUAC activity coefficient model was extended to correlate the polymer solution vapor-liquid equilibrium data. The database can provide the originally measured data, standardized values and correlation parameters of UNIQUAC model.更多还原
