Abstract
Interesting self-assembly behavior of an ABC triblock copolymer in selective solvents for the terminal A and C blocks is reported. The triblock copolymer consists of poly( tert -butyl acrylate)- block -poly(2-cinnamoyloxyethyl methacrylate)- block -poly(glyceryl monomethacrylate) or PtBA- b -PCEMA- b -PGMA, with 107 tBA units, 193 CEMA units, and 115 GMA units. The solvents used are pyridine/methanol with methanol volume fraction f MeOH between 80 and 100%. While pyridine is a good solvent for all of the three blocks, methanol is selective for PtBA and PGMA. At f MeOH = 80% and f MeOH = 90% and at 50 °C, spherical and cylindrical micelles with PtBA and PGMA coronal chains are formed. At f MeOH = 95%, vesicles are formed. Grafted on the outer surface of the vesicles are mostly the PGMA chains and some PtBA chains. The PtBA chains are found by atomic force microscopy and transmission electron microscopy to segregate from the PGMA chains to form circular patches. At f MeOH = 100%, tubular micelle-like aggregates (MAs) coexisted with vesicular MAs. While there have been many reports on morphologies of block copolymer MAs, reports on MAs of ABC triblock copolymers in selective solvents for A and C are rare. Also, there have been very few reports on tubular MAs and MAs with segregated surface chains. These combinations make results of this study unique.

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
