Abstract
The transimidization reaction has been successfully utilized to prepare a series of segmented block copolyimides. The synthesis and polymerization of an AX-type amino imide monomer containing the tetrahydro[5]helicene unit were accomplished. The AX-type amino imide monomer is stable during isolation and purification, owing to its inert X (e.g., N-pyridyl) group, but yet readily underwent a self-transimidization reaction and produced polyimide. Because of the presence of two reactive ends, such an AX-type polyimide could be incorporated into a series of block copolyimides by reaction with commercially available dianhydrides and diamines. All the copolymers showed two distinct glass-transition temperatures, typically around 250 and 430 °C. © 2000 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 38: 3991–3996, 2000

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
