Innentitelbild: Thiol‐Aldehyde Polycondensation for Bio‐based Adaptable and Degradable Phenolic Polymers (Angew. Chem. 36/2023)

A thiol–aldehyde polycondensation was developed for the polymerization of phenolic compounds. In their Research Article (e202305677), Shichao Xu, Liang Yuan et al. found several catalysts for making linear and network-structured phenolic polymers from plant-derived monomers. Since the repeating units are connected via dynamic dithioacetal groups, the cross-linked networks can be reprocessed and oxidatively degraded by DMSO to recover the monomers for reuse.
