Vitrimers are a third class of polymers gathering the mech. properties and solvent resistance of 3D thermosets and the reprocessability of thermoplastics. This unique behavior is due to the triggering of certain covalent exchange reactions that allow the network to rearrange upon application of a stimulus. The constitutive feature of vitrimers is the adoption of a glass-like viscosity during the rearrangement of the network, often due to an associative mechanism for the exchange reaction. Transesterification networks are one of the most studied type of vitrimers that usually require the incorporation of a catalyst, implying the associated drawbacks. Following up on a recent report on catalyst-free transesterification vitrimers in which the ester functions are particularly reactive thanks to the presence of fluorine atoms in α- or β-position, parallel DFT calculations and an exptl. kinetic study on model mols. are presented in order to quant. assess the effect of neighboring fluorinated groups on the transesterification reaction rate.
