Preparation and Characterization of Nitrile Butadiene Rubber (NBR)/Polyoxymethlene (POM) Blends Compatibilized by Maleic Anhydride Grafted POM (MAH-g-POM)
Bibliographic record
Abstract
Maleic anhydride grafted POM (MAH-g-POM) was prepared and used as the compatibilizer for nitrile butadiene rubber (NBR) modified by acetal copolymer (POM) in different proportions. It was found that MAH-g-POM had good compatibilization effect for the blends. Both DSC and XRD results indicated that the process of blending POM with NBR considerably influenced the crystallization of POM. The scanning electron microscopy (SEM) study of tensile fracture surfaces of the blends clearly showed that the compatibility of NBR/POM blends was enhanced with increasing POM content. Mechanical properties indicated that NBR/MAH-g-POM had relatively higher elongation at break but lower tensile strength than NBR/POM blend. The present work will supply a good insight into the formula design and further optimization of polymer composites or blends.

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.
