Understanding the Dissolution Kinetics of a DINCH Plasticized PVC: Experimental Design and Applied Modeling.

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
Polymer dissolution-precipitation recycling is a promising pathway to increase plastic recycling rates. One of the first steps in this process is the dissolution of the plastic, where it is important to understand and predict the dissolution kinetics, specifically for plastic waste. Therefore, the dissolution kinetics of a plasticized poly(vinyl chloride) sample (P-PVC), containing bis(7-methyloctyl) cyclohexane-1,2-dicarboxylate (DINCH), are analyzed in N-methyl-2-pyrrolidinone (NMP), cyclohexanone, methyl ethyl ketone (MEK), and 2-methyltetrahydrofuran (2-MeTHF). Additionally, the effects of the particle size (1090-2990 μm) and temperature (30-60 °C) are studied. As expected, lowering the particle size and increasing the temperature reduced the overall dissolution time. It is also found that the dissolution of the polymer and plasticizer occurred simultaneously, and that the fastest dissolution occurred in NMP, followed by cyclohexanone, MEK, and 2-MeTHF. Finally, both a chain disentanglement model and a first-order model with a diffusion-based rate coefficient are fitted to the experimental data to describe the dissolution behavior of the selected plastic waste. The first is found to be a slightly better description of the P-PVC dissolution profile in NMP, a known good solvent, while the latter is better at describing the dissolution in MEK and 2-MeTHF, the slowest analyzed solvents.
