Abstract

fetched live from OpenAlex

The present work was focused on investigating the potential of using side chain liquid crystalline polymers(SCLCP) as nucleating agents for semicrystalline polymers.For this purpose,two vinyl monomers with liquid crystalline properties were designed and prepared.By means of homopolymerization two side chain liquid crystalline polymers having different architectures were synthesized.The monomers and the polymers obtained were characterized by elemental analysis,FTIR and()~1H-NMR measurements.DSC and HS-POM were employed to study the phase-transition temperatures and mesophase textures for the polymers.The thermal stability of the polymers was measured by TGA.The results showed that the polymers were all thermotropic side chain liquid crystalline polymers with wide liquid crystalline phase temperature range and excellent thermal stability.The effect of one of the SCLCPs used as a nucleating agent in the crystallization of high density polyethylene(HDPE) was investigated by DSC and HS-POM.The results indicated that SCLCP could effectively increase the crystallization temperature,crystallization speed and the crystallinity for HDPE.It was found that the synthesized SCLCP could be an effective nucleating agent for HDPE.

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.
