In this study, a commercial epoxy resin is modified through the integration of functional groups into the network structure to provide superior performance. The present study has demonstrated that it is possible to adapt the curing process to efficiently incorporate these moieties in the final structure of commercial epoxy-based resins. It also evaluates the impact that they have on the final properties of the cured composites. In addition, different approaches have been studied for the incorporation of the functional group, adjusting and adapting the stoichiometry of the system components due to the differences in reactivity caused by the presence of the incorporated reactive groups, with the objective of maintaining comparable ratios of epoxy/amine groups in the formulation. Finally, it has been demonstrated that although the Diels–Alder equilibrium responds under external conditions, such as temperature, different sets of parameters and behaviors are to be expected as the structures are integrated into the thermoset, generating new equilibrium temperatures. In this way, the present research has explored sustainable strategies to enable the recyclability of commercial thermoset systems through crosslinking control and its modification. info:eu-repo/grantAgreement/EC/H2020/101023190/EU/Improving recyclability of thermoset composite materials through a greener recycling technology based on reversible biobased bonding materials This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 101023190-VIBES info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 4.9 2024 POLYMER SCIENCE 19 / 94 = 0.202 2024 Q1 T1 0.918 2024 Polymers and Plastics 2024 Q1 Chemistry (miscellaneous) 2024 Q1 9.7 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Hornero, Carlos De la Flor, Silvia Vilanova, Anna Dieste, Jose Antonio Universidad de Zaragoza (orcid)0000-0001-7178-4285 Castell, Pere 5002 515 Universidad de Zaragoza Dpto.
