Webb14 mars 2024 · Silicones are ubiquitous materials owing to their exceptional mechanical and thermal stability as well as low toxicity. Recycling them has become a relevant target for circular economy purposes. Conventional processes of chemically recycling polysiloxanes allow for the recovery of valuable cyclic monomers. Unfortun Webb14 apr. 2024 · Chemically recyclable polymers that can depolymerize into their constituent monomers are attractive candidates to replace non-recyclable petroleum-derived plastics. However, the physical properties and mechanical strengths of depolymerizable polymers are commonly insufficient for practical applications.
