The organizing committee of the workshop consisted of Professor Busch, Kristina Zentel, Svenja Albus and Laura Dietrich from TU Darmstadt, as well as Professor Kosek, Alexandr Zubov and Adam Bouz from the University of Chemistry and Technology Prague. A total of 15 lectures and 13 posters on the topic of Polymer Reaction Engineering were presented at the workshop. Additionally, the focus of the final day this year was on the topic of Circular Economy.

A total of 32 participants attended the WPPRE, including 21 doctoral students from ten different universities and six representatives from industry. The latter presented their companies and supported the financing of the workshop by sponsoring. The WPPRE 2025 was supported by the following companies BASF, Lummus Technology, SABIC, Tosoh Bioscience, Arlanxeo, Macromolecular Reaction Engineering and Wiley. In addition to the presentations, the poster sessions, joint lunches and dinners offered the opportunity to network with other participants from academia and industry. The program was rounded off with a tour through the old town of Prague on a historic tramcar. For many of the Busch working group, the WPPRE is the first conference they have attended during their doctorate. In 2025, the working group contributed the following posters and presentations:

• Transitiometric Characterization of Peroxide Cocktail Decomposition under Elevated Pressure: Influences of Composition and Process Parameters, Svenja Albus, Markus Busch (poster)
• Deterministic Modeling of the High-Pressure Process for Ethene-Vinyl Acetate-Vinyl Neodecanoate Terpolymerization, Adil Boukhalaf, Anne Rott, Markus Busch (lecture + poster)
• Emulsion polymerization of butyl acrylate and styrene in batch and 3D-printed reactors, Ferel Issa, Kristina Zentel (lecture + poster)
• Modeling of the High-Pressure Copolymerization of Ethene and Acrylic Acid: Integrating Kinetics in Computational Fluid Dynamics Simulations, Alexander Keßler, Laura Dietrich, Markus Busch (lecture + poster)
