Abstract:	In this project, a new family of vitrimeric materials based on the dynamic exchange of disulfide linkages has been developed. Two different monomers have been synthesized, one that contains sulfur-sulfur linkages and the other one without has been used as a reference. Both were characterized using different analytical techniques such as 1H-NMR and FTIR. A set of samples with different formulations have been analysed in order to achieve an appropriate catalytic system which selectively activates the disulfide bond exchange. After evaluating the thermal-mechanical properties of each material and their vitrimeric capabilities using thermal analytical techniques such as DSC, DMA and TGA, among others, a final formulation was chosen. The material was tested in the 3D printer, and its repairing and reprocessing capabilities were evaluated. Finally, it has been proposed possible further alternatives to solve the main problems arised in our work.
