Dielectric Polarization and the Stages of a Macromolecule's Growth
Bibliographic record
Abstract
To investigate the change in the orientation polarization, particularly during the growth of a macromolecule by addition reactions in a liquid, dielectric relaxation spectra of diglycidyl ether of bisphenol A have been studied in real time. It is found that in the plot of the dielectric permittivity, ε ‘, measured at a fixed frequency against the polymerization time, the first step of the (inverted) sigmoid-shape part of the spectrum resembling a relaxational decrease is a dc conduction effect. After this effect vanishes, the equilibrium permittivity, ε s, of the liquid increases with time as covalently bonded molecular clusters form at random sites in the bulk liquid, and the dipole orientational correlation increases as a result of hydrogen bonding between the newly formed OH groups. Thereafter, the macromolecule's continuous growth in the liquid decreases the net dipole moment of the covalently bonded network, which decrease ε s . Thus, after the conductance effect has become negligible, a plot of ε s against the polymerization time shows a maximum. Both the dc conductivity, σ 0, and the distribution parameter for dielectric relaxation decrease with time, and σ 0 follows a scaling equation for gelation. The irreversible increase in relaxation time during a macromolecule's growth is explained in terms of a decrease in the configurational entropy, and a relation between the two is provided.

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.
