Closed-loop recyclability of a biomass-derived epoxy-amine thermoset by methanolysis Open
Epoxy resin thermosets (ERTs) are an important class of polymeric materials. However, owing to their highly cross-linked nature, they suffer from poor recyclability, which contributes to an unacceptable level of environmental pollution. Th…
Phosphorus acid: an asset for flame-retardant sustainable vitrimers Open
Three biobased epoxy resins from vanillic alcohol, linseed oil and cardanol were crosslinked with phosphoric acid to prepare vitrimers.
From vineyards to reshapable materials: α-CF<sub>2</sub> activation in 100% resveratrol-based catalyst-free vitrimers Open
Vitrimers are a class of polymers bridging resistant crosslinked thermosets and recyclable linear thermoplastics. The material presented here contains 86% bio-based carbon, is catalyst-free, durable and recyclable, and features a high Tg.
Synthèse et caractérisation de vitrimères de transestérification sans catalyseur Open
Vitrimers are a type of polymer materials featuring superior resistance to solvents, mechanical properties comparable to thermosets, and the ability to be reprocessed. Their macromolecular network embeds exchangeable bonds responsible for …
Understanding the Reshaping of Fluorinated Polyester Vitrimers by Kinetic and DFT Studies of the Transesterification Reaction Open
Vitrimers are a third class of polymers gathering the mechanical properties and solvent resistance of 3D thermosets and the reprocessability of thermoplastics. This unique behaviour is due to the triggering of certain covalent exchange rea…

Catalyst-free transesterification vitrimers: activation <i>via</i> α-difluoroesters Open
Transesterification vitrimers often require high catalyst loadings to prepare 3D networks reprocessable at moderately high temperature.
Neighboring Group Participation and Internal Catalysis Effects on Exchangeable Covalent Bonds: Application to the Thriving Field of Vitrimer Chemistry Open
Vitrimers constitute a fascinating class of polymer materials that make the link between the historically opposed 3D networks (thermosets) and linear polymers (thermoplastics). Their chemical resistance, reshaping ability, and unique rheol…
