Application of irreversible thermodynamics to the solvent diffusion in an amorphous glassy polymer: A comprehensive model for drying of toluene‐poly(methyl methacrylate) coatings
Bibliographic record
Abstract
Abstract In this work a comprehensive framework for modelling solvent‐polymer mutual diffusion coefficient in the glassy state is proposed. This framework is based on irreversible thermodynamics. In particular, an appropriate transformation is used to show that case‐II diffusion appearing in the glassy state could be reduced to a close‐to‐equilibrium rubbery state where typical equations relating the solvent‐polymer mutual diffusion coefficient with chemical potential and the solvent self‐diffusion coefficient are available. Moreover, this theory is applied to solvent evaporation from a toluene‐poly(methyl methacrylate) film. The toluene evaporation process is modelled as a coupled heat and mass problem with a moving boundary. Model predictions were found to be in satisfactory agreement with available experimental data. It is believed that this work could be used to further study solvent diffusion in the glassy polymer state.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
