Abstract
The influence of polydispersity on the phase behavior of diblock copolymer melts is studied using a self-consistent field theoretic model. A perturbation theory is developed for the polydisperse system, in which the polydispersity index, κ = M w / M n − 1, is taken as a perturbation parameter. Phase diagrams are constructed using the reciprocal space method. It is found that the order−disorder transition boundary shifts to higher temperatures, as predicted by a random phase approximation analysis. For asymmetric polymer distributions, polydispersity favors structures with curved interfaces. The domain spacing of the ordered structures increases with increasing polydispersity index. An analysis of the free energy provides an understanding of the mechanism of these effects.

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
