Hydrolyzable Bio‐Based Bisphenols Enabled by the Tishchenko Reaction for Polyurethane Vitrimers with Closed‐Loop Recyclability

open access: yesAdvanced Science, EarlyView.
This study employs the Tishchenko coupling reaction to obtain bio‐based bisphenols containing degradable ester bonds with 100% atom utilization. Based on these bio‐based bisphenols, a fully bio‐based polyurethane Covalent Adaptable Networks are constructed, while simultaneously endowing the material with closed‐loop recyclability, degradability, and ...
