Processability and reprocessability maps for vitrimers considering thermal degradation and thermal gradients

A lack of fundamental knowledge about the kinetic mechanisms governing the processing and reprocessing of vitrimers forces a trial-and-error procedure to be adopted when choosing treatment conditions. In this work, we develop diagrams to be used as a straightforward tool to decide the curing and the...

The thermal stability of a disulfide containing epoxy has been evaluated by means of thermal analysis methods.
