Propargyl resin derived from biosynthesized oligophenols for the application of high temperature composite matrix
Bibliographic record
Abstract
Abstract A novel addition‐cure‐type propargyloligophenol resin for high‐temperature usage was prepared via a two‐step process: Horseradish Peroxidase (HRP) catalyzed oxidation polymerization of phenols to oligophenols, and Williamson etherification of oligophenols to propargyloligophenols. Propargyloligophenols possess an ideal processability for composite manufacture, i.e. good solubility, low melting point (< 50 °C), and thermal curability. As shown by Differential Scanning Calorimetry (DSC), propargyloligophenol resin upon heating experiences a broad thermal exothermic peak in the range of 175–300 °C peaking at around 260 °C. The cured resin is high‐temperature resistant with an initial decomposition temperature > 400 °C and an anaerobic char yield > 60 % at 700 °C. The mechanical properties of glass fabric‐reinforced propargyloligophenol laminate were superior to those of conventional phenolic resins. The results showed that propargyloligophenol resin is a prospective polymeric matrix for high temperature composites.

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.
