The European Polymer Journal (EPJ) has been serving the scientific community for 50 years, which makes it one of the older macromolecular journals with a broad focus. Since its launch 50 years ago, EPJ has provided a distinguished forum for publications in polymer research, including chemistry, physics, and technology, complemented since 2006 by a special section on macromolecular nanotechnology. Current focal shifts include more emphasis on bio-materials, renewable polymers, and sustainability, while our commitment remains unchanged for the classical sub-fields encompassing synthesis, physics and technology. The Journal’s history is nicely summarized in the Publisher’s Note of EPJ’s Senior Publisher, Dr. Rumen Duhlev, which precedes this Editorial. There is not much the Team of the Editors can add to this regarding the history of the journal. A few personal remarks however could be offered.
