Rheological Study of Polymer--Colloid Complexes of Aluminoxane Particles with Weakly Charged Polyelectrolytes in Semidilute Aqueous Solutions
Bibliographic record
Abstract
Viscoelastic properties of hydrogels based on polymer-colloid complexes of aluminoxane particles with acrylamide-acrylic acid copolymers were studied. Rheometric measurements were performed with an MFR 2000 Fourier microrheometer (GBS, Australia) under the regime of oscillating loads with the use of the dynamic mechanical analysis. It is shown that, with copolymer concentrations above the crossover point, the phase angle decreases abruptly; that is, the elastic characteristics of the gels decline. The maximum elastic properties of the gels for all copolymers are attained at the molar ratio of reagents Z ? 1. The effect of strain rate on relaxation processes in the gels was investigated. It is found that, at low strain rates, irreversible deformations (flow) can take place, and with an increase in frequency, the strength of physical networks formed with participation of aluminoxane particles tends to increase.

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.
