Iminoboronate chemistry enables multifunctional and reprocessable polyphenol-derived vitrimers.

ABSTRACT: Polyphenol-derived vitrimers offer compelling prospects for sustainable materials owing to their intrinsic recyclability, reprocessability and biodegradability. However, practical development remains constrained by structure degradation under harsh reprocessing conditions and the need for sophisticated modifications of the bio-sourced precursors. Herein, we reported a strategy that integrates commercially available polyphenols and low-molecular-weight PDMS through adaptable iminoboronate chemistry, obviating the need for structural modifications. The N-B coordination lowers the activation barriers for both imine and boronic ester exchange, enabling efficient bond rearrangement. The resulting vitrimers exhibited excellent reprocessability under relatively mild conditions while retaining exc
