Bulk Synthesis and Modeling of Living <scp>ROMP</scp> of 1,5‐<scp>C</scp>yclooctadiene for Narrowly Distributed Low Molecular Weight Linear Polyethylenes
Bibliographic record
Abstract
The bulk ring‐opening metathesis polymerization (ROMP) of 1,5‐cyclooctadiene is carried out with a commercially available Grubbs' catalyst, bis(tricyclohexylphosphine)benzylidine ruthenium(IV) dichloride, with and without triphenylphosphine. Bulk ROMP exhibits living polymerization features and yields polyethylene mimics with comparable or improved molecular weight distribution control and similar conversions as solution ROMP. The reaction kinetics and polymer molecular weight development are well‐described by a mathematical model developed using the method of moments. The success of bulk ROMP and the development of the kinetic model show that bulk ROMP can be a viable polymerization pathway for the synthesis of low molecular weight linear polymers with well‐controlled structures.

How this classification was reachedexpand
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.
