Copolymers of Functionalized and Nonfunctionalized Polydicyclopentadiene
Bibliographic record
Abstract
Polydicyclopentadiene (PDCPD) is a thermoset polymer that is valued in industry for its excellent mechanical properties, heat resistance, and chemical tolerance. However, the commercial polymer lacks chemically tunable functionality. Recently, a methyl ester functionalized polydicyclopentadiene (fPDCPD) was shown to offer significantly improved tunability while maintaining the same thermal stability as the unfunctionalized parent polymer. In this report, we describe the synthesis and characterization of poly[(methyl ester functionalized dicyclopentadiene)-stat-(dicyclopentadiene)] copolymers in which the mole fraction of the functionalized, ester-containing monomer, relative to the unfunctionalized dicyclopentadiene monomer, is systematically increased. Our data reveal an ability to tune physical and mechanical properties of the copolymers (e.g., alpha transition and hardness) by changing the monomer ratio and thermal curing time. Importantly, the copolymers retain the same thermal stability as the individual homopolymers, while allowing for increased control over surface energy.

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.
