WebThe Higuchi–Connors phase diagram indicated the formation of weak 1:1 and 1:2 complexes. In addition, the reaction conditions were applied to poly (vinylimidazole) and 1,4-bis (1 H -imidazol-1-yl)butane to obtain functionalized polymer networks and oligomers, which were stable at temperatures up to 300 °C and 200 °C, respectively. Experimental WebMay 15, 2024 · The Higuchi–Connors method indicated an increase of more than 2300 times in the aqueous solubility of NG by HPβCD, as well as a high CE value and appropriate increase in dosage bulk, suggesting that the NG/HPβCD complex has good potential for use as a solid dosage form. Despite these benefits, the subsequent experiments showed that …
