Acyclic Hydrocarbon α,ω-Dienes: From Biomass and Plastic Upcycling to Carbocycles, Precision Polymers, and Cross-Linked Elastomers. [PDF]
ChemSusChemHydrocarbon α,ω‐dienes are mainly produced from steam‐cracking derivatives, but high costs, complexity, and environmental impact limit their use. This review highlights sustainable paths from biomass and plastic upcycling, and surveys catalytic transformations into carbocycles and specialty polymers, emphasizing their role as modular building blocks ...
