1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The global plastic pollution crisis urgently demands closed-loop chemical recycling strategies. While recyclable polymers via olefin metathesis have been widely explored, the development of metal-free methods operating under mild conditions remains a significant challenge. Here, we present the lifecycle design of polar-olefin-derived macrocycles as novel monomers capable of undergoing reversible entropy-driven ring-opening polymerization (ED-ROP) through organic base-catalyzed metathesis of polar olefin bonds. High-molecular-weight polymers were efficiently produced via bulk melt polymerization. Kinetic studies and mass analyses indicated the formation of cyclic polymer topologies through insertion and ring expansion, with polymerization thermodynamically driven by an increase in conformational entropy. By shifting the equilibrium of polar-olefin metathesis in dilute solution, these polymers enable efficient closed-loop depolymerization and monomer recovery. This approach establishes a versatile platform based on polar olefin chemistry, advancing the design of recyclable materials with tailored dynamic functionalities.
