Abstract
The present study investigated the morphological and thermal properties of polystyrene and polyvinyl chlorides blends (PS/PVC). The PS and PVC mixed by the solution casting by using cyclohexanone the ratios presented are 100/0,80/20,50/50,20/80 and 0/100 according to the weight of PS/PVC. Where the mixture formation is confirmed by Fourier transform infrared (FT-IR), thermal gravimetric analysis (TGA), and differential scanning calorimetry (DSC) respectively. The spectral FT-IR results showed that the blend of PS/PVC did not have molecular reactions. The thermal gravimetry was used to achieve the thermal stability of the polymer blends. Two degrees of glass transition temperature were observed for each mixture. The results of DSC supported the absence of miscibility in the blend. The distribution of the phases in the virgin and blends was studied through scanning electron microscopy (SEM).

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
