Engineering Research Equipment Grant: Polymer Solution Thermodynamics Laboratory

建立一个准确而广泛的聚合物溶液性质数据库是聚合物性质预测和建模的一个关键方面。在这个项目中提供的设备将提供在整个聚合物组成范围内的聚合物-溶剂相互作用的测量。实验室将包括一个压电晶体吸收装置，一个反相色谱仪，以及一个汽液平衡装置，使用尺寸排除色谱进行分析。后两种设备都将在同一套自动数据收集和分析系统的控制下。在这一领域建立一个实验实验室将对工业界和科学界产生深远的利益。工业上重要的聚合物和溶剂的研究数据虽然本身很重要，但将在这个实验室中发挥更大的优势，作为性质预测和状态方程研究的基础。宾夕法尼亚州立大学在购买设备方面提供了大量的费用分摊。

The compilation of an accurate and wide-ranging data base of polymer solution properties is a critical aspect of polymer property prediction and modeling. The equipment provided in this project will provide for the measurement of polymer-solvent interactions over the entire range of polymer compositions. The laboratory will include a piezoelectric crystal sorption apparatus, an inverse gas chromatograph apparatus, and a vapor-liquid equilibrium apparatus using size exclusion chromatography for analysis. These latter two pieces of equipment will both be under the control of the same automated data collection and analysis system. The establishment of an experimental laboratory in this area will have far-reaching benefits to the industrial and scientific communities. Data from studies of industrially-important polymers and solvents, while important in their own right, will be used to even greater advantage in this laboratory as the basis for property prediction and equation of state research. The Pennsylvania State University provides significant cost sharing in the purchase of the equipment.
