Abstract

fetched live from OpenAlex

Polyvinyl chloride(PVC) was chemically modified with polyhydromethylsiloxane(PHMS) via reactive processing in a Haake Rheomix 600P mixing mill. Two kinds of PHMS with different contents of Si-H (202 #PHMS and 206 #PHMS) were used to reduce the maximum torque( TQ max ) of PVC. On increasing the 206 #PHMS amount, the equilibrium torque( TQ eq ) of PVC increased slightly and passed through a maximum at 0 2 phr of 206 #PHMS. In contrast, the TQ eq of PVC modified with 202 #PHMS increased continuously with increase in 202 #PHMS content. Furthermore, the gelating melting time for PVC modified with 202 #PHMS was shorter than that for PVC with 206 #PHMS. With addition of PHMS the equilibrium temperature( T eq ) of PVC increased firstly and then decreased. PHMS was able to decrease not only the total energy( TTQ eq ) consumed in the reactive processing but also the consumption rate of energy in the initial period of the reactive processing.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
