Abstract

fetched live from OpenAlex

A new monomer,vinyltriallylsilane(CB_3),having functionnal groups with different hydrosilylation reactivity was designed and synthesized by allylation reaction from vinyltrichlorosilane.Then,photocrosslinkable hyperbranched(poly(siloxysilane)) with terminal allyl groups was prepared via hydrosilylation reaction of vinyltriallylsilane(CB_3) and dimethylbis(dimethylsiloxy)silane(A_2) monomers at the presence of Karstedt catalyst,and characterized by means of FTIR,()~1H-NMR,()~(29)Si-NMR,and SEC/RI/MALLS technology.The polymerization process of A_2 and CB_3 monomers was studied in situ by using FTIR.It was found that silicon hydride would preferentially react with vinyl groups during the reaction. This can cause to the generation of an intermediate with one Si—H and three allyl groups.By using it to conduct further self-polymerization,hyperbranched polymer can be obtained.The degree of branching of the resulting hyperbranched poly(siloxysilane) was calculated to be 0.44 by quantitative()~(29)Si-NMR spectroscopy,and the weight average molecular weight was 12.1 kg/mol with its polydispersity of 2.52.Finally,the UV curing behavior of the resulting polymer initiated with different photoinitors was also investigated.

Full frame distilled prediction

Teacher imitation

Not 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.
