The focus of the Priority Programme is the investigation of dense amorphous polymer phases at or near a solid surface. Particular attention is given to the so-called interphase, i.e. the region of the polymer phase where its properties have not quite reached their bulk values. The thickness of the interphase depends not only on the type of polymer and solid and on their interactions, but also on the property under investigation. The mass density, for example, reaches its bulk value much earlier than the cross-link density of a reactive system. Polymer-solid contacts play an important role in technology, from adhesion and coatings to nanocomposites. Yet, the research of the Priority Programme is aimed at the fundamental understanding of the interface and interphase, and not at particular material combinations for particular applications. The investigations are to be carried out using modern methods of preparation, characterisation and theory.

优先方案的重点是调查固体表面或其附近的致密无定形聚合物相。特别注意所谓的界面相，即聚合物相中其性质尚未完全达到其体积值的区域。界面的厚度不仅取决于聚合物和固体的类型及其相互作用，而且还取决于所研究的性质。例如，质量密度达到其体积值的时间比反应体系的交联密度早得多。聚合物-固体接触在从粘接和涂层到纳米复合材料的技术中发挥着重要作用。然而，优先方案的研究目的是对界面和界面阶段的基本了解，而不是针对特定应用的特定材料组合。调查将使用现代的准备、表征和理论方法进行。
