Healable and Reprocessable PETG-Based Dynamic Vinylogous Urethane Networks.
Article in Macromolecules, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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 growing demand for sustainable materials calls for innovative strategies to extend the lifetime of polymers. In response to this challenge, we explored healable and reprocessable vinylogous urethane (VU) networks derived from commercially available glycol-modified polyethylene terephthalate (PETG). These materials were synthesized via Zn-catalyzed transesterification of PETG with ethylene glycol, end-functionalization of the resulting telechelics with bis-acetoacetate, and subsequent VU network formation using tris-(2-aminoethyl)-amine (TREN). The resulting networks combine high tensile strength (up to 48 MPa), high stiffness (0.9 GPa), and appreciable ductility (elongation at break up to 7%). An optimized network composition was reprocessed multiple times with minimal loss in performance and exhibits highly efficient healing behavior, recovering 95% of its original strength after 15 min at 180 °C. Overall, this work presents a simple and scalable route to transform a commercial high-performance polyester into a reprocessable and healable material that offers extended lifetime and improved sustainability.
