Photolysis of poly-acyl styrene polymers / by Kenneth G. Whiting.
Bibliographic record
Abstract
The following is a study of the long wave (wavelength >300 nm) photolysis \nof a series of poly acyl styrenes, in particular, poly-p-acetyl-styrene (PPAS), polyp- \npropionyl-styrene (PPPS), poly-o-acetyl-styrene (POAS), poly-o-proponylstyrene \n(POPS). \nAll photoreactions are initiated from the carbonyl triplet. It is seen that in \nthe solid state, below Tg the main photoprocesses that take place in all systems are Norrish I cleavage and photoreduction. In addition, the ortho polymers have the \nproper structure to allow for photoenolization. Gas product analysis of these ortho \npolymers, in the solid state below Tg suggest evidence for ground state control. \nTransient spectroscopy does indicate the presence of enol formation in these ortho \npolymers. Viscosity studies on solutions showed that secondary reactions with \nthese polymers include competitive cross linking and chain scission. There is a \ndefinite solvent effect observed for all of these systems and the solvent quality has \nan effect on the balance of these secondary reactions. A detailed explanation of this \nsolvent effect is discussed.

How this classification was reachedexpand
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; both teacher heads agree on what is shown here.
