Diversification of aliphatic C-H bonds in small molecules and polyolefins through radical chain transfer

Timothy J. Fazekas et al.

Summary: This study reports an approach to achieve diverse functionality on hydrocarbons by utilizing radical chain transfer. By using an easily prepared reagent, a range of functionalizations on small molecules and polyolefins can be achieved. This method has also been applied in the processing of plastic waste and enables the introduction of ionic functionality on polyolefins, transforming them into elastomers with high-value properties.

Upcycling Plastic Wastes into Value-Added Products by Heterogeneous Catalysis

Tian Tan et al.

Summary: Plastics play important roles in modern society, but their landfilling and discarding as waste contribute to environmental pollution and carbon loss, posing high risks to ecosystems and human health. Current physical recycling methods are limited to thermoplastic recycling and suffer from quality deterioration. Catalytic upcycling has emerged as a promising strategy to treat plastic waste by upgrading it into value-added products under mild conditions. This review highlights recent advances in the development of efficient heterogeneous catalysts and useful strategies for upcycling plastics into various valuable chemicals and materials.

The Critical Role of Process Analysis in Chemical Recycling and Upcycling of Waste Plastics

Scott R. Nicholson et al.

Summary: There is a pressing need to develop new technologies for the circularity of synthetic polymers due to the accumulation of waste plastics and their impact on climate change. Chemical recycling offers a promising solution by converting waste plastics into molecular intermediates for remanufacturing. This paper defines classes of chemical recycling and upcycling and presents general process concepts for the recycling of mixed plastics waste. A framework for techno-economic analysis and life cycle assessment is also provided to evaluate the effectiveness of different recycling approaches.

Mechanically Diverse Gels with Equal Solvent Content

Sergei S. Sheiko et al.

Summary: In this study, a new strategy to independently tune the gel modulus by regulating network strand flexibility with brushlike polymers is reported. This approach overcomes the issue of simultaneous impact of cross-link density on both gel swellability and mechanical properties in traditional gels, and has broad practical applications.

Circularity in mixed-plastic chemical recycling enabled by variable rates of polydiketoenamine hydrolysis

Jeremy Demarteau et al.

Summary: Chemical circularity in mixed-polymer recycling becomes possible by controlling the rates of depolymerization of polydiketoenamines (PDK) through molecular engineering. The stepwise deconstruction of mixed-PDK is chemospecific, allowing the recovery of a certain subset of materials in their pristine condition during the recycling process.

Closed-loop chemical recycling of thermosetting polymers and their applications: a review

Yanlin Liu et al.

Summary: This review discusses the closed-loop recycling of novel thermosets, including hydrolysis recycling and dynamic reaction recycling. Hydrolysis recycling allows recovered thermosets to have the same structure and properties as the original resin, but improving monomer recovery remains a challenge. Dynamic reaction recycling enables 100% recovery rate, but at the cost of lower performance of the recovered resin.

Thermodynamics and Stereochemistry of Diels-Alder Polymer Networks: Role of Crosslinker Flexibility and Crosslinking Density

Qing Zhou et al.

Summary: Dynamic covalent polymer networks crosslinked through Diels-Alder reactions show promise as self-healing, 3D-printable materials. Control parameters include crosslinker flexibility and density, influencing shape reconfigurability. Thermodynamics are dominated by entropic effects, with thermally unstable endo crosslinks converting to stable exo adducts for shape reconfiguration.

Leveling the cost and carbon footprint of circular polymers that are chemically recycled to monomer

Nemi Vora et al.

Summary: Mechanical recycling of polymers downgrades their usability, while chemical recycling offers a more sustainable way to recover chemical feedstocks. The cost and carbon footprint of chemically recycled PDKs are significantly lower than producing virgin resin, providing a strong incentive for recovering and recycling future polymer waste.

Light-Mediated Synthesis and Reprocessing of Dynamic Bottlebrush Elastomers under Ambient Conditions

Chungryong Choi et al.

Summary: A novel grafting-through polymerization strategy was introduced to synthesize dynamic bottlebrush polymers and elastomers using light to construct a disulfide-containing backbone. The key starting material, alpha-lipoic acid (LA), is commercially available, inexpensive, and biocompatible. The resulting bottlebrush elastomers exhibit high gel fractions and tunable shear moduli, with the added benefit of dynamic disulfide bonds allowing for self-healing and on-demand chemical degradation.
