Vitrimers are chemically cross-linked networks that can rearrange their topology without decreasing their cross-linking density thanks to exchangeable links present in the network. As a result, vitrimers can be reshaped and recycled at will while being insoluble at every temperature. In this presentation, the design and synthesis of vitrimers made of polymers prepared by chain-growth polymerization will be discussed. Their synthesis in solution or in the melt, using reactive processing, as well as their ability to be processed multiple times with thermoplastic techniques will be presented. Finally, the thermomechanical and chemical resistances of these vitrimers will exemplified and compared to that of their thermoplastic precursors.
