The Electron Induced Reactive Compounding was developed as a novel process for reactive modification and mixing of polymers. This process opened the way to create unique polymer materials in the fields of compounds, blends and modified polymers. Using the experiences from the starting discontinuous processing with relatively simple lab equipment a special kneader for a continuous process was developed and homemade in a laboratory scale. The process and material variations developed for the discontinuous kneader were successful transferred in continuous processes with an average throughput of about one kg/h. The principles of the process and the technical realization in lab scale and pilot scale will be explained. Different examples of materials development (reactive compounding, blending, chain modification) using this method will be shown. The industrial potential as well as the known and the expected limits will be illustrated.
