• present work, bio-based dinitrones were prepared from acrylated and crotonated isosorbide with benzaldoxime. They were employed as cross-linkers for unsaturated bio-based polyesters from isosorbide, itaconic acid and succinic acid. The thermal cross-linking could be followed by oscillatory measurements
