) were used as model systems and reacted with dimethyl itaconate to further characterize the 1,3-dipolaric cycloaddition.
Keywords: bio-basedpolyesters; cross-linkers; dinitrones; 1,3-dipolar cycloaddition; isosorbide; Introduction
Nitrones represent a class of compounds with a versatile use as
present work, bio-based dinitrones were prepared from acrylated and crotonated isosorbide with benzaldoxime. They were employed as cross-linkers for unsaturated bio-basedpolyesters from isosorbide, itaconic acid and succinic acid. The thermal cross-linking could be followed by oscillatory measurements
