Abstract
A hyperbranched polymer terminated by unsaturated double bonds (HBS) was synthesized and applied in emulsion copolymerization of acrylic monomers,butyl acrylate and methyl methacrylate.The polymerization mechanism,properties of the copolymers and the influence of HBS on the crosslinking structure of copolymers were investigated.The results showed that the acrylates emulsion polymerization process in the presence of HBS was stable,and crosslinked latex particles with average diameter less than 100 nm were obtained.FT-IR measurements of the latex copolymers also showed that the unsaturated terminal groups of HBS are all accessible to polymerization without trapping inside the hyperbranched macromolecular structure,and thus,the polymer networks in which HBS act as multi-arms crosslink points come into being.The emulsion polymerization rate and thermal stablity of the latex copolymers increase,the latex particle size decreases with the increase in HBS content.

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
