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 permanent cross-links that give thermosets their strength and durability also make them difficult to recycle. Here, we present a green, scalable strategy for the chemical deconstruction of poly(dicyclopentadiene) (pDCPD) thermosets and composites using metathesis-based chemical recycling. Key findings include the identification of cyclopentyl methyl ether as a "green" processing solvent for mild deconstruction and an understanding of the catalytic fragmentation mechanism wherein both ring-closing metathesis and chain transfer pathways are present. The deconstruction protocol is shown to be effective for a variety of pDCPD samples produced via distinct ring-opening metathesis polymerization (ROMP) curing methods, including frontal-ROMP, photoROMP, and thermal ROMP, as well as with commercial thermoset formulations and fiber-reinforced composites. As a proof of concept for future translatability, embedded electronics, glass fibers, pristine carbon fibers, and >90% recovery of polymer fragments are demonstrated. Last, a detailed life cycle analysis indicates that this approach offers a viable (high credit) alternative to contemporary thermoset disposal and incineration, opening a path toward closed-loop recycling of high-performance pDCPD materials.
