Fast Upcycling of Poly(ethylene terephthalate) into Catalyst-Free Vitrimers

Shan-Song Wu et al.

Summary: We developed a catalyst-free technique for the synthesis of transesterification-based PET vitrimers, using TGDDM as a reactant in a melt reaction. The TGDDM content was found to affect the reaction mechanism and chemical structure of the final products. At different TGDDM contents, different structures of PET vitrimers were obtained, which exhibited enhanced heat resistance and creep resistance. The facile fabrication technique showed great potential for upcycling PET into vitrimers in large-scale production.

Recyclable thermosets based on modified epoxy-amine network polymers

Lynn Anderson et al.

Summary: The development of recyclable thermoset materials with high performance requires designing recyclability into the molecular structure. This paper presents a single stage process using liquid epoxy resins and aliphatic amines polymerized in the presence of n-butyl diboronic ester to create epoxy-amine-dioxazaborocane materials with tunable physical properties. The mechanical (thermal) recycling and reprocessing of the thermoset show retention of Young's modulus and ultimate tensile strength. Importantly, an efficient and low-cost process for chemical recycling, disassembly, and dissolution is demonstrated using pinacol (diol) or mono-functional phenylboronic ester.

End-of-life upcycling of polyurethanes using a room temperature, mechanism-based degradation

Ephraim G. Morado et al.

Summary: A mechanism for degrading polymers called cyclization-triggered chain cleavage (CATCH cleavage) that achieves dual requirements of strength and degradability has been reported. CATCH cleavage features a glycerol-based acyclic acetal unit as a trap for controlled chain breaks. Organic acid induces transient chain breaks with subsequent cyclization to fully depolymerize the polymer backbone at room temperature. This strategy has the potential for upcycling and may be applicable to various synthetic polymers and their waste streams.

Chemical Upcycling of Conventional Polyureas into Dynamic Covalent Poly(aminoketoenamide)s

Youwei Ma et al.

Summary: Chemical upcycling of polymers has become an emerging strategy to convert post-consumer waste into valuable chemicals and materials. However, due to the high stability of the chemical bonds in many polymers, their chemical modification is often challenging. In this study, a versatile approach for the upcycling of linear and cross-linked polyureas was developed using acetylacetone. The resulting compounds can be reacted with aromatic isocyanates to form highly dynamic aminoketoenamide bonds, enabling the preparation of healable and reprocessable poly(aminoketoenamide) networks through thermal treatment without any catalyst.

Circular Upcycling of Bottlebrush Thermosets

Daixuan Zhang et al.

Summary: The inability to re-process thermosets hinders their utility and sustainability. An ideal material should combine closed-loop recycling and upcycling capabilities. This trait is realized in polydimethylsiloxane bottlebrush networks using thermoreversible Diels-Alder cycloadditions to enable both reversible disassembly into a polymer melt and on-demand reconfiguration to an elastomer of either lower or higher stiffness. The crosslink density was tuned by loading the functionalized networks with a controlled fraction of dormant crosslinkers and crosslinker scavengers, such as furan-capped bis-maleimide and anthracene, respectively. The resulting modulus variations precisely followed the stoichiometry of activated furan and maleimide moieties, demonstrating the lack of side reactions during reprocessing. The presented circularity concept is independent from the backbone or side chain chemistry, making it potentially applicable to a wide range of brush-like polymers.
