Abstract
Oligomers of triacylglycerols (TAGs) are derived from the self-metathesis of vegetable oils and are sought for a variety of applications, in particular waxes. A series of model dimers and quatrimers of TAGs with controlled structures were synthesized and characterized by 1 H NMR and 13 C NMR. Their thermal stability, crystallization, and melting behavior were investigated using TGA and DSC. The relationship of oligomeric structure to thermal properties was found to adhere well to predictive trends. Although the effect of saturation on the phase behavior was the most dramatic, with differences in crystallization temperature up to 62 °C, isomerism and molecular mass were shown to affect crystallization significantly, leading to differences of up to 30 °C. The findings of the study show that the thermal parameters of the oligomers can be adjusted in a very broad range by saturation, isomerism, and size, making the development of a large variety of biosourced functional lubricants and waxes possible.

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
