Abstract
ABSTRACT Fourier transform infrared spectroscopy was used to detect changes or degradation in chain structure of PC/ABS specimens after being exposed to three hygrothermal conditions. The two main absorbance peaks of interest are associated with carbonyl and hydroxyl groups due to the oxidation of butadiene in the ABS component. The changes to these groups were evident in earlier work during thermal aging of this blend but were not found in this hygrothermal study. However, the increase in intensity within the hydroxyl region for two of the conditions was attributed to bulk water diffusion in the material. When viewed together with results published earlier by our research group, the changes driven by bulk moisture diffusion are reversible. © 2014 Wiley Periodicals, Inc. J. Appl. Polym.

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 it
