Reusable Polyphenol Building Blocks Enable Recyclable Epoxy‐Amine Thermosets via Methanolysis
Angewandte Chemie, EarlyView.A biobased epoxy–amine platform was developed using functional building blocks derived from polyphenols. These thermosets exhibited tunable mechanical and thermal properties, together with efficient, catalyst‐free chemical recycling via methanolysis. Beyond the recovery of reusable building blocks, the recycled polyols could be further upcycled into ...
