Small‐Particle High‐Solid‐Content Bimodal Latexes: Highly Crosslinked Small Particles as Pseudo‐Inert Nanofillers
Bibliographic record
Abstract
Abstract High‐solid‐content low‐viscosity bimodal latexes with very small particles (<200 nm) are obtained using two emulsion polymerization approaches. In the first approach, the PSD is controlled by using highly crosslinked nanolatex particles (<30 nm) as seeds for the small mode to minimize their growth during the growth of the large mode. These particles are shown to grow at a volumetric rate that is 25 times lower than the larger particles. Latexes with 57 wt% solids content and viscosities <1400 mPa · s at 20 s −1 are produced. The second approach is based on the re‐nucleation of the small particles by addition of a shot of surfactant in the presence of large particles to produce bimodal latexes. Latexes with 60 wt% solid content with viscosity of 490 mPa · s at 20 s −1 are produced using this approach. magnified image

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
