Abstract
A novel grafted copolymer with two different types of side chains was synthesized via a combination of grafting-onto and grafting-from strategy. Graft copolymer with one side chains polybutadiene-graft-polystyrene (PB-g-PS) was first synthesized though the grafting-onto method. Following the subsequent grafting-from method, the second kind of side chain was introduced to the copolymer with anionic ring open polymerization of ethylene oxide, obtaining dual-grafted copolymer polybutadiene-graft-(polystyrene; poly(ethylene oxide)) (PB-g-(PS;PEO)). By this combined strategy, linear and star-shaped dual-grafted copolymer were synthesized. The resulting dual-grafted copolymers had controlled molecular weights and narrow molecular weight distributions (Mw/Mn < 1.20). The thermal behavior of this dual-grafted copolymer bearing glassy and crystalline side chains was determined by differential scanning calorimetry (DSC), revealing that poly(ethylene oxide) grafts underwent confined crystallization, and the star-shaped copolymer had more confinement effects than did the linear ones.

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
