Reusing Chemically Recycled Cross-Linked Matrix from Succinic Acid–Epoxidized Linseed Oil

Notably, Rec-ELO displayed a higher glass-transition temperature and a broader relaxation profile, indicative of increased network heterogeneity. Advanced kinetics studies further highlighted differences in the apparent curing behavior between formulations from virgin and recycled compounds, as evidenced by Differential Scanning Calorimetry (DSC). These differences were attributed to lower reactive group concentration effects, reduced mobility, and the heterogeneous nature of the recycled polyacid fraction.

These findings demonstrate that solvolysis effectively allows the recovery of valuable materials from biobased thermoset recycling, offering a sustainable approach to reducing waste and reliance on virgin resources.
