Morphology and properties of organoclay modified polycarbonate/poly(methyl methacrylate) blend
Bibliographic record
Abstract
Abstract Virgin and organoclay modified polycarbonate (PC)/poly(methyl methacrylate) (PMMA) (30/70 w/w) blends were prepared by melt‐mixing of PC, PMMA, and organically modified montmorillonite (OMMT). The morphology of OMMT modified PC/PMMA blend with two different weight percents of OMMT was studied using scanning electron microscopy, transmission electron microscopy (TEM), and X‐ray diffraction (XRD). The size of the phase‐separated domains decreased dramatically with increasing the content of OMMT. XRD patterns and TEM observations revealed that silicate layers were intercalated and nicely dispersed in the blend matrix. Differential scanning calorimetry analyses showed efficient mixing of two immiscible polymers in the presence of OMMT. The blend nanocomposites showed greatly improved mechanical properties when compared with the same blend sample without OMMT. Finally, the opaque immiscible PC/PMMA blend became translucent after modification with OMMT addition. POLYM. ENG. SCI., 46:1121–1129, 2006. © 2006 Society of Plastics Engineers

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
