Industry/University Cooperative Research Project: Polymer Solution Thermodynamics (with International Cooperation)

本研究计划的目的是获得聚合物和溶剂混合物行为的实验数据，并开发方法来关联和预测这种行为。为了获得一种预测方法，将基于Sanchez-Lacombe格孔理论或广义Van der Waals配分函数方法建立新的群贡献状态方程。此外，还应考虑到多色散的影响。一个计算机数据库正在建立现有的文献数据和新的实验数据在这个程序中获得。利用反气相色谱法和压电吸附技术收集二元相互作用的数据，利用粒径排除色谱法研究液-液平衡分析三元体系的数据。实验测量将在广泛的溶剂浓度范围内进行，使用一套精心挑选的精心制备的单分散聚合物，在许多情况下，这些聚合物将由工业DIPPR赞助商提供。pi与丹麦技术大学聚合物实验室的工作人员建立了密切的合作关系。这个精心构建的理论见解、实验仪器、实践目标、工业咨询和国际合作网络为发起与聚合物解决方案有关的严重问题的新的有力攻击提供了一个独特的机会。

The objective of this research program is to obtain experimental data on the behavior of mixtures of polymers and solvents and to develop methods to correlate and predict this behavior. In order to obtain a predictive method, a new group-contribution equation of state is to be developed based either on the Sanchez-Lacombe lattice-hole theory or the generalized Van der Waals partition function approach. In addition, the effects of polydispersion are to be taken into account. A computer database is being created on available literature data and the new experimental data obtained in this program. Data are being collected on binary interactions by use of inverse gas chromatography and piezoelectric sorption techniques and on ternary systems by the study of liquid-liquid equilibria using size exclusion chromatography for analysis. Experimental measurements will be taken over a wide range of solvent concentrations with a carefully selected set of carefully prepared monodispersed polymers, which in a number of cases will be provided by the industrial DIPPR sponsors. The PIs have established close collaboration with the workers in the polymer laboratory at the Technical University of Denmark. This carefully built network of theoretical insights, experimental apparatus, practical objectives, industrial consultation, and international cooperation provides a unique opportunity to launch a new and vigorous attack on the serious problems relating to polymer solutions.
