The long-range objective of this research program is to develop methods for the correlation and prediction of the equilibrium thermodynamic behavior of pure polymers and polymer-solvent solutions. This is to include effects of pressure and temperature on density, vapor-liquid and liquid equilibria, and systems containing multiple solvents and/or polymers. In order to achieve this goal, extensive and reliable data are needed for the model developments. Data bases are being assembled containing evaluated literature data for the various types of systems. In order to pursue the development of a dependable group contribution model, more accurate data will be collected. The laboratory established under a previous NSF equipment grant is used for this purpose. A new group contribution model is being developed based on a lattice-fluid model of the polymer-solvent systems. The program is being coordinated with a complementary effort at the Technical University of Denmark.

该研究计划的长期目标是开发关联和预测纯聚合物和聚合物-溶剂溶液的平衡热力学行为的方法。这包括压力和温度对密度、汽液和液体平衡的影响，以及含有多种溶剂和/或聚合物的体系。为了实现这一目标，模型开发需要广泛和可靠的数据。正在汇编数据库，其中载有各种类型系统的评价文献数据。为了开发可靠的集团贡献模型，将收集更准确的数据。根据之前的NSF设备赠款建立的实验室就是用于这一目的。基于聚合物-溶剂体系的晶格-流体模型，正在开发一种新的基团贡献模型。该项目正在与丹麦技术大学的一项补充工作进行协调。
