Closed-loop recyclable cross-linked polymeric materials via dynamic transetherification

Abstract

This work communicates the closed-loop recyclability and dynamic property tunability in benzylic ether-based cross-linked polymers. Remarkably, the polymers were fully degradable via transetherification, and the monomers were recovered in high yields. The recovered monomers were used to re-synthesize the polymers with pristine-like material properties. Further on, the tunability of dynamic properties was investigated by a systematic increase in the inter-crosslink distance by four methylene groups, which showed strong effects on the stress relaxation property.
