Abstract

fetched live from OpenAlex

Photoinitiated cationic polymerization is useful wherever the lack of oxygen inhibition, low shrinkage and formation of polymers with good adhesion properties are essential. Rates and conversions for cationic polymerizations of epoxycyclohexylmethyl-epoxycyclohexane carboxylate (ECHC) with various cationic photoinitiators and their blends were compared. Glass-transition temperatures of polymers were determined by dynamic mechanical analysis. When photopolymerizations of ECHC with initiator blends were compared with single-initiator systems, strong synergies leading to high polymerization rates and conversions were discovered for blends of diaryliodonium hexafluoroantimonate (IA) with tolylcumyliodonium tetrakis(pentafluorophenyl)borate (IB), and cumenecyclopentadienyliron(II) hexafluorophosphate with IA and IB. Mechanisms responsible for the discovered synergies are proposed.

Teacher imitation

Not 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.
