WebFeb 25, 2024 · The ability to reverse controlled radical polymerization and regenerate the monomer would be highly beneficial for both fundamental research and applications, yet this has remained very challenging to achieve. Herein, we report a near-quantitative (up to 92%) and catalyst-free depolymerization of various linear, bulky, cross-linked, and functional … WebOct 15, 2024 · 1. Introduction. The wide application of plastics has resulted in the accumulation of large quantities of discarded plastics [1], plastics production surged from 15 million tons in 1964 to above 300 million tons in 2024 globally [2], and the growth of plastic waste exceeds the burden of mitigating plastic pollution [3].Plastic waste …
WebReversing reversible deactivation radical polymerization (RDRP) to regenerate the original monomer is an attractive prospect for both fundamental research and industry. However, current depolymerization strategies are often applied to highly heat-tolerant polymers with a specific end-group and can only be performed in a specific solvent.
