Daftar Isi:
- <p>Cationic water-soluble chitosan was synthesized by conjugating 3-chloro-hydroxy-propyltrimethylammonium chloride onto chitosan chain. Varying the molar ratio of 3-chloro-hydroxy-propyltrimethylammonium chloride to chitosan from 3:1 to 6:1 produced chitosan with variation of substitution degree. The molecular weight of chitosan was determined by intrinsic viscosity measurements in 0.25 M acetic acid / 0.25 M sodium acetate at 25oC. FTIR measurements were performed to analyze the chemical composition of the cationic water-soluble chitosan. 1H NMR spectra were obtained to confirm the successful conjugation onto chitosan chain. Water solubility of obtained cationic polymers was measured using UV-vis spectrophotometer at 600 nm.</p>
