Abstract
The phase behavior of ternary homopolymer/gradient copolymer blends is studied theoretically using a multiblock model of gradient copolymers. Critical lines and Lifshitz points of the blends are determined by a random phase approximation analysis. Phase diagrams and microphase structures of the blends are studied using self-consistent mean-field theory. It is discovered that the chain gradient distribution has a significant effect on the phase behavior of the blends. When the chain gradient distribution is gradual, a larger amount of copolymers and a higher incompatibility are needed for the formation of a microphase. In addition, the ability of copolymer domains to absorb homopolymers decreases, whereas the solubility of copolymers in homopolymer matrix increases, as the gradient distribution becomes gradual. Another important effect is that gradient copolymers lead to a broad interface between two incompatible polymers. These results indicate that interfacial structure and morphology of these blends can be fine-tuned by specifically designed gradient distributions.

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
