Abstract: Methods for recycling thermoset polymers, particularly by changing them into dynamic networks with the use of an appropriate catalyst solution which transforms the thermoset polymer into a vitrimer-like composition. The methods include the step of swelling a crosslinked thermoset polymer in a solution including a catalyst, whereby the catalyst diffuses into the thermoset polymer, in particular into the thermoset network. Upon removal of the liquid portion of the solution, such as solvent, the catalyst facilitates the occurrence of exchange reactions at elevated temperatures, rendering the system a dynamic network. The vitrimerized composition having the thermoset polymer and catalyst is recyclable and processable and thus suitable for many end uses.
