Antioxidant and Degradable Poly(Squaryl Thioester) Networks
Macromolecular Materials and Engineering, Volume 311, Issue 6, June 2026.Herein, squaryl dichloride is introduced as a novel monomer to the realm of thermosets. First, squaryl dichloride is prepared from squaric acid, and then it is reacted with multifunctional thiol compounds to prepare novel networks. Overall, it is demonstrated that squaryl dichloride is a suitable monomer for the fabrication of thermally stable, acid ...

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance
Advanced Functional Materials, Volume 36, Issue 40, 18 May 2026.A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation
