Closed‐Loop Recycling of Vinylogous Urethane Vitrimers
, 2023 Devising energy-efficient strategies for the depolymerization of plastics and the recovery of their structural components in high yield and purity is key to a circular plastics economy. Here, we report a case study in which we demonstrate that vinylogous

Macromolecular Materials and Engineering, 2022 In this work, vitrimeric elastomers based on functionalized poly(dimethylsiloxane) are realized. By exploiting reactions of epoxide functional groups with carboxylic acids in the presence of a covalently bonded amine catalyst, dynamic networks are formed

Fast Upcycling of Poly(ethylene terephthalate) into Catalyst-Free Vitrimers
, 2023 We reported a catalyst-free technique to fabricate transesterification-based poly(ethylene terephthalate) (PET) vitrimers via melt reacting PET with N,N′-tetraglycidyldiaminodiphenyl methane (TGDDM) in several minutes. We investigated the effect of TGDDM

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy
Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).
