An experimental approach to the development and validation of Group Interaction Modelling

基团相互作用模型（GIM）是一种将聚合物的结构与其热机械性能联系起来的模型。本研究项目的目的是使用一系列实验技术和条件对单一材料测量一系列材料特性（动态模量，热膨胀系数，热容量等），并直接将结果与GIM的预测进行比较。这将从结构简单的聚合物开始，如聚乙烯（PE），然后转移到具有特定侧基的聚合物，从而获得更坚实的内部，以了解材料结构如何导致聚合物的不同性能。

Group Interaction Modelling (GIM) is a model developed to relate the structure of polymers to their thermomechanical properties. The aim of this research project is to measure a range of material properties (dynamic moduli, thermal expansion coefficient, heat capacity etc.) using a range of experimental techniques and conditions for a single material and directly compare the results to the predictions made by GIM. This will be done, starting from a simple-structured polymer such as polyethylene (PE) and later moving to polymers with specific side groups, thus getting a more solid inside for how material structure results in different properties for polymers.
