Solvent-Based Separation of PA6 and PET Using Solubility Data from Differential Scanning Calorimetry.
Article in Industrial & engineering chemistry research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
To minimize plastic pollution and prevent further extraction of fossil feedstock, the circular economy for polymers offers a promising solution. As an integral part of the circular economy to close material loops, solvent-based recycling enables the separation of mixed plastic waste into pure component streams without altering the polymer structure but requires reliable solubility data of polymers in solvents. We present a standardized differential scanning calorimetry (DSC) protocol to determine decrystallization and precipitation temperatures of polymers in various solvents and apply it to the challenging separation of polyamide 6 (PA6) and polyethylene terephthalate (PET). The DSC method enables quantitative solubility analysis even above solvent boiling points and shows good agreement with a visual polythermal cloud point method while offering higher objectivity and additional phase transition enthalpies. Temperature-dependent solubility data for nine solvents reveal that methanol, ethanol, propylene glycol, dimethyl sulfoxide, and water are selective solvents for PA6 over PET. A proof-of-concept PA6-PET separation using methanol yields recycled polymers with near-virgin properties under mild conditions (109 °C, ∼4 bar), demonstrating the process relevance of the obtained DSC data for solvent selection in low-energy, solvent-based recycling processes.
