The Cover Feature shows the desirable life-cycle for polyolefins, leading from small building olefinic blocks to polymeric materials present everywhere in our daily life and use of transition metal catalysis cut recycle polymers back smaller molecules or new blocks. In their Review, M. Hapke co-workers compiled state-of-the-art chemical recycling polyethylenes polypropylenes at rather low react...

Reversing controlled radical polymerization and regenerating the monomer has been a long-standing challenge for fundamental research practical applications. Herein, we report highly efficient depolymerization method various polymethacrylates synthesized by reversible addition-fragmentation chain-transfer (RAFT) polymerization. The process, which does not require any catalyst, exhibits near-quan...

Prebiotic chemical reactions would have been greatly aided by a process whereby living materials could have been recycled under conditions of limiting resources. Recombination of RNA fragments is a viable means of recycling but has not been demonstrated. Using systems based on the Azoarcus group I intron ribozyme, computational Monte Carlo studies indicate that a moderate level of recycling act...
