Review of Enhancement Effect of Supercritical Carbon Dioxide on Melt Phase Polycondensation
Bibliographic record
Abstract
The new research advances in the technologies of melt phase polycondensation and swollen solid phase polycondensation due to the presence of supercritical CO2 were reviewed.The effects of supercritical CO2 on the melt phase polycondensation and the solid phase polycondensation with respect to the production of polyester,polycarbonate,and nylon-66 were discussed.Significant advantages of using supercritical CO2 in improving the polycondensation kinetic rates and /or increasing the molecular weight of the resultant products were demonstrated in the above mentioned systems.It is concluded that the mechanism via which supercritical CO2can significantly improve the polycondensation processes is that the presence of supercritical CO2enhances both of the thermodynamic equilibrium driving force and the dynamic mass transport rate.

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.
