The aim of the project is the development of a method for quantitative description of the selective wetting and distribution kinetics of reinforcing hybrid-filler-systems in rubber blends and the corresponding heterophasic elastomers made therefrom by cross-linking. Thus the relationships between rubber compound formulation, mixing technology, morphology development and resulting properties shall be characterized and explained based on well-defined model systems. Therefore, in-line characterization methods during the rubber specific technological mixing process will be combined with analytical methods. By means of the fundamental knowledge achieved, the phase-specific localization of the filler components during rubber compounding, which is a decisive factor for the physico-mechanical properties of the elastomers, shall be describable apriori. The developed method will be experimentally verified using material systems whose formulations are expanded from application-oriented point of view.

该项目的目的是开发一种方法，用于定量描述橡胶共混物中增强混合填料系统的选择性润湿和分布动力学，以及通过交联由其制成的相应多相弹性体。因此，橡胶化合物配方，混合技术，形态发展和最终性能之间的关系应根据明确定义的模型系统进行表征和解释。因此，橡胶特定工艺混炼过程中的在线表征方法将与分析方法相结合。通过所获得的基础知识，在橡胶配混过程中填料组分的相特异性局部化（这是弹性体物理机械性能的决定性因素）应可先验地描述。所开发的方法将使用材料系统，其配方从面向应用的角度扩展实验验证。
